DBT基因编码功能及结构描述
支链α-酮酸脱氢酶复合物（BCKD）是一种线粒体内酶复合物，参与支链氨基酸异亮氨酸、亮氨酸和缬氨酸的分解bckd复合物被认为是由24个转酰酶（e2）亚基和相关的脱羧酶（e1）、脱氢酶（e3）和调节亚基组成。这个基因编码转酰酶（E2）亚单位该基因突变导致枫糖尿病，2型。已经描述了选择性剪接的转录变体，但其生物学有效性尚未确定。[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]
