Identification
NameN-terminal acetyltransferase B complex catalytic subunit NAT3
Synonyms
  • NatB complex subunit NAT3
  • NatB Nalpha terminal acetyltransferase 3
Gene NameNAT3
Enzyme Class
Biological Properties
General FunctionInvolved in N-acetyltransferase activity
Specific FunctionCatalytic subunit of the NatB N-terminal acetyltransferase, which catalyzes acetylation of the amino- terminal methionine residues of all proteins beginning with Met- Asp or Met-Glu and of some proteins beginning with Met-Asn or Met- Met. NatB acetylates TPM1 protein and regulates tropomyocin-actin interactions
