检测编号:NA0050002
基因 MCCC1 与疾病
3-甲基巴豆酰辅酶A羧化酶是亮氨酸中间代谢产物3-甲基巴豆酰辅酶A转化成3-甲基戊烯二酸单酰辅酶A的一个羧化酶,由6个α-β组合体形成一个功能性3-甲基巴豆酰辅酶A羧化酶,在线粒体中发挥作用。MCCC1编码其α亚基,α亚基上有一个维生素B结合区。已发现至少30种突变,大部分是点突变,也有少量是缺失突变。

基因摘要 |
This gene encodes the large subunit of 3-methylcrotonyl-CoA carboxylase. This enzyme functions as a heterodimer and catalyzes the carboxylation of 3-methylcrotonyl-CoA to form 3-methylglutaconyl-CoA. Mutations in this gene are associated with 3-Methylcrotonylglycinuria, an autosomal recessive disorder of leucine catabolism. [provided by RefSeq, Jul 2008]. |
基因 MCCC2 与疾病
3-甲基巴豆酰辅酶A羧化酶是亮氨酸中间代谢产物3-甲基巴豆酰辅酶A转化成3-甲基戊烯二酸单酰辅酶A的一个羧化酶,由6个α-β组合体形成一个功能性3-甲基巴豆酰辅酶A羧化酶,在线粒体中发挥作用,MCCC2编码其β亚基,已经发现40多种突变,大多是点突变。

基因摘要 |
This gene encodes the small subunit of 3-methylcrotonyl-CoA carboxylase. This enzyme functions as a heterodimer and catalyzes the carboxylation of 3-methylcrotonyl-CoA to form 3-methylglutaconyl-CoA. Mutations in this gene are associated with 3-Methylcrotonylglycinuria, an autosomal recessive disorder of leucine catabolism. [provided by RefSeq, Jul 2008]. |
