A	PF11838	ERAP1-like C-terminal domain (ERAP1_C)	ERAP1-like C-terminal domain	This large domain is composed of 16 alpha helices organized as 8 HEAT-like repeats. This domain forms a concave face that faces towards the active site of the peptidase.	Domain
A	PF01433	Peptidase family M1 domain (Peptidase_M1)	Peptidase family M1 domain	Members of this family are aminopeptidases. The members differ widely in specificity, hydrolysing acidic, basic or neutral N-terminal residues. This family includes leukotriene-A4 hydrolase Swiss:P09960, this enzyme also has an aminopeptidase activ ...	Members of this family are aminopeptidases. The members differ widely in specificity, hydrolysing acidic, basic or neutral N-terminal residues. This family includes leukotriene-A4 hydrolase Swiss:P09960, this enzyme also has an aminopeptidase activity [1].	Domain
A	PF17900	Peptidase M1 N-terminal domain (Peptidase_M1_N)	Peptidase M1 N-terminal domain	This domain is found at the N-terminus of aminopeptidases from the M1 family.	Domain
