   Research Summary

Introduction – Ubiquinone (coenzyme Q or Q) functions in cells as a redox-active coenzyme of mitochondrial and plasma membrane electron transport, as well as an essential lipid soluble antioxidant. Human dietary supplementation with Q appears to have beneficial effects in slowing the progression of neuro- and muscle-degenerative diseases. However, Q is also involved in generating reactive oxygen species, through the adventitious reduction of dioxygen to superoxide by the ubisemiquinone radical, normally generated during mitochondrial electron transport. Thus, it is not clear how dietary supplementation with Q impacts the Dr. Jekyll/Mr. Hyde aspects of Q function. Cells are capable of synthesizing Q, but much remains to be learned about the sites of its synthesis, mechanisms of inter- and intra-cellular transport, and the regulation and enzymology of its biosynthesis. Research in my laboratory identified eight of the eleven polypeptides required for Q biosynthesis. The goals of my research are to characterize the Coq polypeptides responsible for production of Q and to determine how their activity can be modulated for optimal health.

Research Overview -

(1) We discovered a new Q biosynthetic pathway and showed that yeast are able to synthesize Q from a new aromatic ring precursor, para-aminobenzoic acid (pABA) [77]. This pathway operates in addition to the classic Q biosynthetic pathway that emanates from 4-hydroxybenzoic acid (4HB). We suggest a mechanism where Schiff base mediated deimination forms DMQ6 quinone, thereby eliminating the nitrogen contributed by pABA. This scheme results in the convergence of the 4HB and pABA pathways in eukaryotic Q biosynthesis and has implications regarding the action of pABA-based antifolates. This work is funded by a grant from NSF.

(2) The findings we made in the yeast model have shed much light on diseases resulting from Q deficiency [82, 85]. We showed that human Coq8 and Coq6 polypeptide homologues function to rescue the respective yeast coq mutants [80, 81]. We discovered that yeast Coq8p, and its human homologue ADCK3 function in the phosphorylation of Coq3p, Coq5p, and Coq7p [80]. The kinase function of Coq8p is proposed to be important in the maintenance or formation of a high molecular mass Coq polypeptide complex, which is required for Q biosynthesis.

(3) Over-expression of Coq8p in many of the yeast coq null mutants restores steady state levels of Coq polypeptides. This has been a particularly important discovery, because the yeast coq null mutants (coq3-coq9) previously accumulated the same early Q-intermediate. Coq8 over-expression has enabled us to detect late-stage Q-intermediates that were previously elusive [86]. Finally, we used synthetic analogues of 4-hydroxybenzoic acid to bypass deficient biosynthetic steps and showed that 2,4-dihydroxybenzoic acid is able to restore Q6 biosynthesis and respiratory growth in a coq7 null mutant over-expressing Coq8. The over-expression of Coq8 and the use of analogues of 4-HB represent new tools to elucidate the Q biosynthetic pathway. These recent discoveries are depicted in Figure 1.

Figure 1

Figure 1. S. cerevisiae Q6 biosynthetic pathway: accumulation of Q6 biosynthetic intermediates caused by the over-expression of Coq8 in Dcoq strains. The classic Q biosynthetic pathway is shown in path 1 emanating from 4-hydroxybenzoic acid (4-HB). Coq1 (not shown) synthesizes the hexaprenyl-diphosphate tail which is transferred by Coq2 to 4-HB to form 3-hexaprenyl-4-hydroxybenzoic acid (HHB).  R represents the hexaprenyl tail present in all intermediates from HHB to Q6. Alternatively, path 2 shows para-aminobenzoic acid (pABA) is prenylated by Coq2 to form 3-hexaprenyl-4-aminobenzoic acid (HAB). Both HHB and HAB are early Q-intermediates, readily detected in each of the coq null strains (Dcoq3-Dcoq9). The numbering of the aromatic carbon atoms used throughout this study is shown on the reduced form of Q6, Q6H2. Coq8 over-expression in certain Dcoq strains leads to the accumulation of the following compounds: 4-AP, 3-hexaprenyl-4-aminophenol; 4-HP, 3-hexaprenyl-4-hydroxyphenol; HHAB, 3-hexaprenyl-4-amino-5-hydroxybenzoic acid; HMAB, 3-hexaprenyl-4-amino-5-methoxybenzoic acid; DDMQ6, the oxidized form of demethyl-demethoxy-Q6H2; IDMQ6, 4-imino-demethoxy-Q6; DMQ6H2, demethoxy-Q6H2. IDDMQ6H2, 2-demethyl-4-amino-demethoxy-Q6H2 and DHHB, 3-hexaprenyl-4,5-dihydroxybenzoic acid are shown but have not been detected in this study. Black dotted arrows (from path 2 to path 1) designate the replacement of the C4-amine with a C4-hydroxyl and correspond to the C4-deamination reaction. A putative mechanism to replace the C4-imino group with the C4-hydroxy group is shown in bracket in blue on IDMQ6 but could also occur on IDDMQ6 (not shown). 4-AP and 4-HP which are formed upon inhibition of the C5-hydroxylation catalyzed by Coq6 are shown in red. Analogues of 4-HB and pABA allowing the bypass of certain steps in Q biosynthesis are indicated in green. Steps defective in the Dcoq9 strain are designated with a red asterisk.

4) In collaboration with Retrotope, we have employed novel isotope-reinforced polyunsaturated fatty acids (PUFAs) that reveal the importance of Q as an essential antioxidant [79, 87]. Polyunsaturated fatty acids (PUFA) undergo autoxidation and generate reactive carbonyl compounds that are toxic to cells and associated with apoptotic cell death, age-related neurodegenerative diseases, and atherosclerosis. PUFA autoxidation is initiated by the abstraction of bis-allylic hydrogen atoms. Replacement of the bis-allylic hydrogen atoms with deuterium atoms (termed site-specific isotope-reinforcement) arrests PUFA autoxidation due to the isotope effect. We investigate the effects of different isotope-reinforced PUFAs and natural PUFAs on autoxidation kinetics, and on the viability of coenzyme Q-deficient Saccharomyces cerevisiae coq mutants and wild-type yeast subjected to copper stress. Cells treated with a C11-BODIPY fluorescent probe to monitor lipid oxidation products show that lipid peroxidation precedes the loss of viability due to H-PUFA toxicity. We show that replacement of just one bis-allylic hydrogen atom with deuterium is sufficient to arrest lipid autoxidation. In contrast, PUFA reinforced with two deuterium atoms at mono-allylic sites remain susceptible to autoxidation. Surprisingly, yeast treated with a mixture of approximately 20%:80% isotope-reinforced D-PUFA: natural H-PUFA are profoundly protected from lipid autoxidation-mediated cell killing. Our findings show that inclusion of only a small fraction of PUFA deuterated at the bis-allylic sites is sufficient to profoundly inhibit the chain reaction of non-deuterated PUFA. .

Figure 2

Fig. 2. Replacement of bis-allylic H atoms with deuterium (D) arrests autoxidation of PUFA. A theoretical chain reaction is depicted where a single initiation event producing a lipid peroxyl radical (denoted by –OO•) starts a chain reaction of lipid autoxidation that in the presence of O2, may continue indefinitely and produce many molecules of lipid peroxides; susceptible phospholipid molecules containing a PUFA acyl chain are designated by a red dot. The presence of 20% isotope-reinforced PUFA (denoted by a black dot) inhibit (or slow) chain propagation. Propagation is inhibited for PUFA neighboring the D-PUFA.
