Calcium Binding
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_01975, ECO:0000269|PubMed:16761197};
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). {ECO:0000255|HAMAP-Rule:MF_01975, ECO:0000269|PubMed:16761197}.
Temperature Dependency BIOPHYSICOCHEMICAL PROPERTIES: Temperature dependence: Optimum temperature is 80-90 degrees Celsius. {ECO:0000269|PubMed:16761197};
PH Dependency BIOPHYSICOCHEMICAL PROPERTIES: pH dependence: Optimum pH is 7. {ECO:0000269|PubMed:16761197};
