Identification
Name: Phosphoserine
Description:Phosphoserine is phosphoric acid ester of serine. As a constituent (residue) of proteins, its side chain can undergo O-linked glycosylation. It is one of three amino acid residues that are commonly phosphorylated by kinases during cell signalling. Phosphorylated serine residues are often referred to as phosphoserine.

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
Gene Name:
aphA
Locus Tag:
PA1409
Molecular weight:
38 kDa
Reactions
A phosphate monoester + H(2)O = an alcohol + phosphate.
General function:
Involved in metabolic process
Specific function:
Catalyzes the reversible conversion of 3- phosphohydroxypyruvate to phosphoserine and of 3-hydroxy-2-oxo-4- phosphonooxybutanoate to phosphohydroxythreonine. Is involved in both pyridoxine and serine biosynthesis
Gene Name:
serC
Locus Tag:
PA3167
Molecular weight:
39.9 kDa
Reactions
O-phospho-L-serine + 2-oxoglutarate = 3-phosphonooxypyruvate + L-glutamate.
4-phosphonooxy-L-threonine + 2-oxoglutarate = (3R)-3-hydroxy-2-oxo-4-phosphonooxybutanoate + L-glutamate.
