Protein attributes

Sequence length	360 AA.
Sequence status	Complete.
Protein existence	Evidence at transcript level

General annotation (Comments)

Function	As well as its role in the urea cycle, may be involved in tissue remodeling.
Catalytic activity	L-arginine + H2O = L-ornithine + urea.
Cofactor	Binds 2 manganese ions per subunit By similarity.
Pathway	Nitrogen metabolism; urea cycle; L-ornithine and urea from L-arginine: step 1/1.
Subunit structure	Homotrimer By similarity.
Tissue specificity	Expressed at differing tadpole stages in tail, intestine, hindlimb and trunk region. Most abundant in tadpole tail.
Developmental stage	First detected in neurula (stage 16/17). Highest levels in whole tadpole found around stage 47/48. In the intestine, increased levels are found during metamorphosis (stages 58-64). Low levels expressed in hindlimb until stage 66 after which, levels dramatically increase. In the tail, a constant high level of expression is found throughout metamorphosis.
Induction	By thyroid hormone (T3).
Sequence similarities	Belongs to the arginase family.
