Identification
Name: Phosphotyrosine
Description:Phosphotyrosine is a tyrosine (an amino acid) with a phosphate attached to its aromatic ring. Tyrosine (abbreviated as Tyr or Y) is one of the 22 amino acids that are used by cells to synthesize proteins. It is a non-essential amino acid with a polar side group. (Wikipedia) Tyrosine phosphorylation and dephosphorylation plays a role in cellular signal transduction and possibly in cell growth control. (PubChem) In Pseudomonas aeruginosa, phosphotyrosine can act as a noncompetitive inhibitor of the enzyme biosynthetic ornithine decarboxylase. (EcoCyc)

Enzymes

General function:
Involved in acid phosphatase activity
Specific function:
Dephosphorylates several organic phosphomonoesters and catalyzes the transfer of low-energy phosphate groups from phosphomonoesters to hydroxyl groups of various organic compounds. Preferentially acts on aryl phosphoesters. Might function as a broad-spectrum dephosphorylating enzyme able to scavenge both 3'- and 5'-nucleotides and also additional organic phosphomonoesters
