(According to Entrez Gene, Wikipedia's Gene Wiki,
UniProtKB/Swiss-Prot, and/or UniProtKB/TrEMBL)
About This Section

 EntrezGene summary for NAT5:
NAT5 is a component of N-acetyltransferase complex B (NatB). Human NatB performs cotranslational
N(alpha)-terminal acetylation of methionine residues when they are followed by asparagine
(Starheim et al., 2008 [PubMed 18570629]).[supplied by OMIM]

UniProtKB/Swiss-Prot: NAT5_HUMAN, P61599
Function: Seems to be involved in N-acetylation (By similarity)
