Protein

Polynucleotide 5'-triphosphatase

Gene

CTL1

Organism
Saccharomyces cerevisiae (strain ATCC 204508 / S288c) (Baker's yeast)
Status
Reviewed-Annotation score: Annotation score: 4 out of 5-Experimental evidence at protein leveli

Functioni

Probably involved in an RNA processing event other than mRNA capping. Releases gamma-phosphate from the 5'-end of RNA to produce a diphosphate terminus.

Catalytic activityi

A 5'-phosphopolynucleotide + H2O = a polynucleotide + phosphate.

Cofactori

Mg2+, Mn2+Note: Magnesium and/or manganese. Specific for polynucleotide RNA in the presence of magnesium, but becomes specific for nucleotide triphosphates in the presence of manganese.
