Protein

Protein phosphatase 2C homolog 1

Gene

PTC1

Organism
Saccharomyces cerevisiae (strain ATCC 204508 / S288c) (Baker's yeast)
Status
Reviewed-Annotation score: Annotation score: 5 out of 5-Experimental evidence at protein leveli

Functioni

It has a serine and a weak tyrosine phosphatase activity with ratios of serine to tyrosine phosphatase activity as high as 200:1. It is essential for growth or germination at 37 degrees Celsius. May have a role in the heat shock response. Involved in tRNA splicing and cell separation.

Miscellaneous

Present with 1520 molecules/cell in log phase SD medium.1 Publication

Catalytic activityi

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

Cofactori

Mg2+, Mn2+Note: Binds 2 magnesium or manganese ions per subunit. Manganese is about 20 times more efficient than magnesium.
