| catalytic Activity | CATALYTIC ACTIVITY: Reaction=Release of N-terminal amino acids, preferentially methionine, from peptides and arylamides.; EC=3.4.11.18; Evidence={ECO:0000255|HAMAP-Rule:MF_01974}; |
| DNA Binding | |
| EC Number | 3.4.11.18 |
| Enzyme Function | FUNCTION: Removes the N-terminal methionine from nascent proteins. The N-terminal methionine is often cleaved when the second residue in the primary sequence is small and uncharged (Met-Ala-, Cys, Gly, Pro, Ser, Thr, or Val). Requires deformylation of the N(alpha)-formylated initiator methionine before it can be hydrolyzed. {ECO:0000255|HAMAP-Rule:MF_01974, ECO:0000269|PubMed:19688379}. |
| Temperature Dependency | BIOPHYSICOCHEMICAL PROPERTIES: Temperature dependence: Optimum temperature is 55 degrees Celsius. It retained half of its activity after 10 min of incubation at 55 degrees Celsius. {ECO:0000269|PubMed:19688379, ECO:0000269|PubMed:20363127}; |
