CC   -!- FUNCTION: Catalyzes the cleavage of 5-oxoproline to form L-glutamate
CC       coupled to the hydrolysis of ATP to ADP and inorganic phosphate.
CC       {ECO:0000255|HAMAP-Rule:MF_00691}.
CC   -!- CATALYTIC ACTIVITY:
CC       Reaction=5-oxo-L-proline + ATP + 2 H2O = ADP + H(+) + L-glutamate +
CC         phosphate; Xref=Rhea:RHEA:10348, ChEBI:CHEBI:15377,
