Protein

p-aminobenzoyl-glutamate hydrolase subunit B

Gene

abgB

Organism
Escherichia coli (strain K12)
Status
Reviewed-Annotation score: Annotation score: 4 out of 5-Experimental evidence at protein leveli

Functioni

Component of the p-aminobenzoyl-glutamate hydrolase multicomponent enzyme system which catalyzes the cleavage of p-aminobenzoyl-glutamate (PABA-GLU) to form p-aminobenzoate (PABA) and glutamate. AbgAB does not degrade dipeptides and the physiological role of abgABT should be clarified.2 Publications

    Links to similar proteins from the UniProt Reference Clusters (UniRef) at 100%, 90% and 50% sequence identity:
    100%UniRef100 combines identical sequences and sub-fragments with 11 or more residues from any organism into one UniRef entry.
    90%UniRef90 is built by clustering UniRef100 sequences that have at least 90% sequence identity to, and 80% overlap with, the longest sequence (a.k.a seed sequence).
    50%UniRef50 is built by clustering UniRef90 seed sequences that have at least 50% sequence identity to, and 80% overlap with, the longest sequence in the cluster.
