    Protein Summary

    The protein YP_749235.1 is annotated as Succinylglutamate desuccinylase/aspartoacylase. YP_749235.1 belongs to PFAM PF04952 AstE_AspA which includes Succinylglutamate desuccinylase EC:3.1.-.- that catalyses the fifth and last step in arginine catabolism by the arginine succinyltransferase pathway. The family also include aspartoacylase EC: which cleaves acylaspartate into a fatty acid and aspartate. 

    Further information on these proteins may be found in the Topsan Zinc Peptidase  page.

    The protein has an unknown ligand (UNL) bound in the active site near Zn. The UNL resembles a derivative of Glutamate which could be related to Succinyl-Glutamate.
