AC MF_02102; DC Protein; auto TR HAMAP; MF_02102; -; 1; level=0 XX Names: PTCase XX ID PTC DE RecName: Full=Putrescine carbamoyltransferase; DE Short=PTC; DE Short=PTCase; DE EC=2.1.3.6; DE AltName: Full=Putrescine transcarbamoylase; DE AltName: Full=Putrescine transcarbamylase; GN Name=ptcA; XX CC -!- FUNCTION: Catalyzes the phosphorolysis of N-carbamoylputrescine to form CC carbamoyl phosphate and putrescine. Is involved in the degradation CC pathway of the polyamine agmatine. CC -!- CATALYTIC ACTIVITY: CC Reaction=carbamoyl phosphate + putrescine = H(+) + N- CC carbamoylputrescine + phosphate; Xref=Rhea:RHEA:21936, CC ChEBI:CHEBI:15378, ChEBI:CHEBI:43474, ChEBI:CHEBI:58228, CC ChEBI:CHEBI:58318, ChEBI:CHEBI:326268; EC=2.1.3.6; CC -!- PATHWAY: Amine and polyamine biosynthesis; putrescine biosynthesis via CC agmatine pathway; putrescine from N-carbamoylputrescine (transferase CC route): step 1/1. CC -!- SUBUNIT: Homotrimer. CC -!- SUBCELLULAR LOCATION: Cytoplasm. CC -!- SIMILARITY: Belongs to the aspartate/ornithine carbamoyltransferase CC superfamily. PTCase family.
