Enzyme Information

3.1.1.61
Protein-glutamate methylesterase.
based on mapping to UniProt Q9WYN9
Protein L-glutamate O(5)-methyl ester + H(2)O = protein L-glutamate + methanol.
-!- Hydrolyzes the products of EC 2.1.1.77, EC 2.1.1.78, EC 2.1.1.80 and EC 2.1.1.100.
3.5.1.44
Protein-glutamine glutaminase.
based on mapping to UniProt Q9WYN9
Protein L-glutamine + H(2)O = protein L-glutamate + NH(3).
-!- Specific for the hydrolysis of the gamma-amide of glutamine substituted at the carboxyl position or both the alpha-amino and carboxyl positions, e.g., L-glutaminylglycine and L-phenylalanyl-L- glutaminylglycine.
