Protein attributes

Sequence length	306 AA.
Sequence status	Complete.
Protein existence	Inferred from homology

General annotation (Comments)

Function	Catalyzes the formation of putrescine from agmatine By similarity. HAMAP-Rule MF_01418
Catalytic activity	Agmatine + H2O = putrescine + urea. HAMAP-Rule MF_01418
Cofactor	Manganese By similarity.
Pathway	Amine and polyamine biosynthesis; putrescine biosynthesis via agmatine pathway; putrescine from agmatine: step 1/1. HAMAP-Rule MF_01418
Disruption phenotype	Cells show a delay in differentiation to swarmer cells and are unable to migrate effectively on agar surfaces. Putrescine restores normal cell differentiation and migration ability. Ref.1
Sequence similarities	Belongs to the arginase family. Agmatinase subfamily.
Sequence caution	The sequence AAP55488.1 differs from that shown. Reason: Erroneous initiation.
