N-acetyltransferase B complex, non-catalytic subunit (IPR019183)

Short name: N-acetylTrfase_B_cplx_non-cat

Family relationships



This is the non-catalytic subunit of the N-terminal acetyltransferase B complex (NatB). The NatB complex catalyses the acetylation of the amino-terminal methionine residue of all proteins beginning with Met-Asp or Met-Glu and of some proteins beginning with Met-Asn or Met-Met. In Saccharomyces cerevisiae (Baker's yeast) this subunit is called MDM20 and in Schizosaccharomyces pombe (Fission yeast) it is called Arm1. NatB acetylates the Tpm1 protein and regulates and tropomyocin-actin interactions. This subunit is required by the NatB complex for the N-terminal acetylation of Tpm1 [PMID: 12808144].
