RP   NUCLEOTIDE SEQUENCE [LARGE SCALE MRNA].
RC   TISSUE=Kidney;
RG   NIH - Xenopus Gene Collection (XGC) project;
RL   Submitted (MAY-2004) to the EMBL/GenBank/DDBJ databases.
CC   -!- FUNCTION: Has omega-amidase activity. The role of omega-amidase is to
CC       remove potentially toxic intermediates by converting 2-oxoglutaramate
CC       and 2-oxosuccinamate to biologically useful 2-oxoglutarate and
CC       oxaloacetate, respectively. {ECO:0000250|UniProtKB:Q9NQR4}.
CC   -!- CATALYTIC ACTIVITY:
CC       Reaction=2-oxoglutaramate + H2O = 2-oxoglutarate + NH4(+);

CC   -!- SUBUNIT: Homodimer. {ECO:0000250|UniProtKB:Q9NQR4}.
CC   -!- SUBCELLULAR LOCATION: Cytoplasm {ECO:0000250|UniProtKB:Q9NQR4}.
CC   -!- SIMILARITY: Belongs to the carbon-nitrogen hydrolase superfamily.
CC       NIT1/NIT2 family. {ECO:0000305}.
