ACADSB（acyl-CoA dehydrogenase short/branched chain），癌症关联基因，基因ID：36，短/支链酰基辅酶a脱氢酶（ACADSB）是脂肪酸或支链氨基酸代谢中催化酰基辅酶a衍生物脱氢的酶家族中的一员底物特异性是定义该基因家族成员的主要特征。acadsb基因产物对短支链酰基辅酶a衍生物（s）-2-甲基丁基辅酶a具有最大的活性，但也与其他2-甲基支链底物和短直链酰基辅酶a发生显著反应。该cDNA编码线粒体前体蛋白，该蛋白在线粒体导入时被裂解，并预测产生约43.7 kDa的成熟肽。[由RefSeq提供，2008年7月]Short/branched chain acyl-CoA dehydrogenase(ACADSB) is a member of the acyl-CoA dehydrogenase family of enzymes that catalyze the dehydrogenation of acyl-CoA derivatives in the metabolism of fatty acids or branch chained amino acids. Substrate specificity is the primary characteristic used to define members of this gene family. The ACADSB gene product has the greatest activity towards the short branched chain acyl-CoA derivative， (S)-2-methylbutyryl-CoA， but also reacts significantly with other 2-methyl branched chain substrates and with short straight chain acyl-CoAs. The cDNA encodes for a mitochondrial precursor protein which is cleaved upon mitochondrial im。
