Protein

Serine/threonine-protein phosphatase 5

Gene

PP5

Organism
Solanum lycopersicum (Tomato) (Lycopersicon esculentum)
Status
Reviewed - Annotation score: 5 out of 5- Experimental evidence at protein leveli

Functioni

Isoform 2 dephosphorylates phosphorylated phytochromes, with a preference toward Pfr forms, and enhances phytochrome-mediated photoresponses (By similarity). Can use para-nitrophenylphosphate (pNPP) and phosphorylated casein as substrate at pH 7.5 and 5.0.By similarity1 Publication

Catalytic activityi

[a protein]-serine/threonine phosphate + H2O = [a protein]-serine/threonine + phosphate.

Cofactori

Mn2+By similarityNote: Binds 2 manganese ions per subunit.By similarity

Enzyme regulationi

Activated by linoleic acid, linolenic acid, oleic acid, and arachidonic acid (AA).

Isoform 2 (identifier: Q84K11-2) [UniParc]FASTAAdd to Basket

Also known as: 55 kDa isoform

The sequence of this isoform differs from the canonical sequence as follows:
     158-228: Missing.

Note: Partial isoform 2 (148-485) lacking TPR repeats exhibits enhanced activity at pH 7.5 but not at pH 5.0 with phosphocasein as substrate. This partial protein is in addition inhibited by okadaic acid.
