支鏈α-酮酸脫氫酶復合物（BCKD）是一種線粒體內酶復合物，參與支鏈氨基酸異亮氨酸、亮氨酸和纈氨酸的分解bckd復合物被認為是由24個轉酰酶（e2）亞基和相關的脫羧酶（e1）、脫氫酶（e3）和調節亞基組成。這個基因編碼轉酰酶（E2）亞單位該基因突變導致楓糖尿病，2型。已經描述了選擇性剪接的轉錄變體，但其生物學有效性尚未確定。[由RefSeq提供，2008年7月]
The branched-chain alpha-keto acid dehydrogenase complex (BCKD) is an inner-mitochondrial enzyme complex involved in the breakdown of the branched-chain amino acids isoleucine, leucine, and valine. The BCKD complex is thought to be composed of a core of 24 transacylase (E2) subunits, and associated decarboxylase (E1), dehydrogenase (E3), and regulatory subunits. This gene encodes the transacylase (E2) subunit. Mutations in this gene result in maple syrup urine disease, type 2. Alternatively spliced transcript variants have been described, but their biological validity has not been determined. [provided by RefSeq, Jul 2008]
