Characterization of the formation of branched short-chain fatty acid:CoAs for bitter acid biosynthesis in hop glandular trichomes.
Xu H., Zhang F., Liu B., Huhman D.V., Sumner L.W., Dixon R.A., Wang G.
Bitter acids, known for their use as beer flavoring and for their diverse biological activities, are predominantly formed in hop (Humulus lupulus) glandular trichomes. Branched short-chain acyl-CoAs (e.g. isobutyryl-CoA, isovaleryl-CoA and 2-methylbutyryl-CoA), derived from the degradation of bran ... >> More
Bitter acids, known for their use as beer flavoring and for their diverse biological activities, are predominantly formed in hop (Humulus lupulus) glandular trichomes. Branched short-chain acyl-CoAs (e.g. isobutyryl-CoA, isovaleryl-CoA and 2-methylbutyryl-CoA), derived from the degradation of branched-chain amino acids (BCAAs), are essential building blocks for the biosynthesis of bitter acids in hops. However, little is known regarding what components are needed to produce and maintain the pool of branched short-chain acyl-CoAs in hop trichomes. Here, we present several lines of evidence that both CoA ligases and thioesterases are likely involved in bitter acid biosynthesis. Recombinant HlCCL2 (carboxyl CoA ligase) protein had high specific activity for isovaleric acid as a substrate (K cat /K m = 4100 s(-1) M(-1)), whereas recombinant HlCCL4 specifically utilized isobutyric acid (Kcat/K m = 1800 s(-1) M(-1)) and 2-methylbutyric acid (Kcat/K m = 6900 s(-1) M(-1)) as substrates. Both HlCCLs, like hop valerophenone synthase (HlVPS), were expressed strongly in glandular trichomes and localized to the cytoplasm. Co-expression of HlCCL2 and HlCCL4 with HlVPS in yeast led to significant production of acylphloroglucinols (the direct precursors for bitter acid biosynthesis), which further confirmed the biochemical function of these two HlCCLs in vivo. Functional identification of a thioesterase that catalyzed the reverse reaction of CCLs in mitochondria, together with the comprehensive analysis of genes involved BCAA catabolism, supported the idea that cytosolic CoA ligases are required for linking BCAA degradation and bitter acid biosynthesis in glandular trichomes. The evolution and other possible physiological roles of branched short-chain fatty acid:CoA ligases in planta are also discussed. << Less

Molecular identification and characterization of two medium-chain acyl-CoA synthetases, MACS1 and the Sa gene product.
Fujino T., Takei Y.A., Sone H., Ioka R.X., Kamataki A., Magoori K., Takahashi S., Sakai J., Yamamoto T.T.
In this study, we identified and characterized two murine cDNAs encoding medium-chain acyl-CoA synthetase (MACS).

In this study, we identified and characterized two murine cDNAs encoding medium-chain acyl-CoA synthetase (MACS). One, designated MACS1, is a novel protein and the other the product of the Sa gene (Sa protein), which is preferentially expressed in spontaneously hypertensive rats. Based on the murine MACS1 sequence, we also identified the location and organization of the human MACS1 gene, showing that the human MACS1 and Sa genes are located in the opposite transcriptional direction within a 150-kilobase region on chromosome 16p13.1. Murine MACS1 and Sa protein were overexpressed in COS cells, purified to homogeneity, and characterized. Among C4-C16 fatty acids, MACS1 preferentially utilizes octanoate, whereas isobutyrate is the most preferred fatty acid among C2-C6 fatty acids for Sa protein. Like Sa gene transcript, MACS1 mRNA was detected mainly in the liver and kidney. Subcellular fractionation revealed that both MACS1 and Sa protein are localized in the mitochondrial matrix. (14)C-Fatty acid incorporation studies indicated that acyl-CoAs produced by MACS1 and Sa protein are utilized mainly for oxidation. << Less
