Protein Family Models

These peptidases have gamma-glutamyl hydrolase activity; that is they catalyse the cleavage of the gamma-glutamyl bond in poly-gamma-glutamyl substrates. They are structurally related to Pfam:PF00117, but contain extensions in four loops and at the C terminus [1]. [1]. 11953431. Three-dimensional structure of human gamma -glutamyl hydrolase.

aminodeoxychorismate/anthranilate synthase component II is part of a complex that catalyzes the two-step biosynthesis of 4-amino-4-deoxychorismate (ADC), a precursor of p-aminobenzoate (PABA), and anthranilate, an intermediate in the biosynthesis of L-tryptophan, respectively

This HMM describes the glutamine amidotransferase domain or peptide of the tryptophan-biosynthetic pathway enzyme anthranilate synthase or of the folate biosynthetic pathway enzyme para-aminobenzoate synthase. In at least one case, a single polypeptide from Bacillus subtilis was shown to have both functions. This model covers a subset of the sequences described by the PFAM HMM GATase.
