The protein

Catalyzed reaction/ biological activity

• degradation of glycine. [protein|58CF62EBA28E77668A0B5319142C8AC20D81CD8A|gcvH] shuttles the methylamine group of glycine from [protein|20175DF9FCF07C34A05C572B089C33D1E1FE6DF2|gcvPB] to [protein|F6F449170276055E6D60D89E9E17A152A82CA166|gcvT] (according to UniProt)
• assembly of lipoate, and transfer of the cofactor to [protein|2F40086E35FA32136B9A89C530A86D714FE9460C|pdhC], [protein|02BA02D10DFB06E51101D8CF76BCF5BED94D7CA2|odhB], [protein|C4B6C3EE560C8BD353FEABB1A607C89C20DC8D34|acoC], and [protein|262C9FD20C7A70B6F1FEB57735FA800F38EAB25A|bkdB]

Protein family

• gcvH family (single member, according to UniProt)

[wiki|Domains]

• [wiki|Lipoyl-binding domain] (aa 22-104) (according to UniProt)

[wiki|Cofactors]
