Molecular cloning of rat acss3 and characterization of mammalian propionyl-CoA synthetase in the liver mitochondrial matrix.

Among the three acyl-CoA synthetase short-chain family members (ACSS), ACSS3 is poorly characterized. To characterize ACSS3, we performed molecular cloning and protein expression of rat acss3 and determined its intracellular localization, tissue distribution, and substrate specificity. Transient expression of rat ACSS3 in HeLa cells resulted in a 10-fold increase of acetyl-CoA synthetase activity compared with that in control cells. The acss3 transcripts are expressed in a wide range of tissues, with the highest levels observed in liver tissue followed by kidney tissue. Subcellular fractionation using liver tissue showed that ACSS3 is localized into the mitochondrial matrix. Among the short-chain fatty acids examined, recombinant ACSS3, purified from Escherichia coli cells transformed with the plasmid containing rat acss3, preferentially utilized propionate with a KM value of 0.19 mM. Knockdown of acss3 in HepG2 cells resulted in a significant decrease of ACSS3 expression level and propionyl-CoA synthetase activity in cell lysates. Levels of ACSS3 in the liver and the activity of propionyl-CoA synthetase in the mitochondria were significantly increased by fasting. These results suggested that ACSS3 is a liver mitochondrial matrix enzyme with high affinity to propionic acid, and its expression level is upregulated under ketogenic conditions. << Less

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.

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.

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
