Protein

Hydroxymethylpyrimidine/phosphomethylpyrimidine kinase THI20

Gene

THI20

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

Catalyzes the phosphorylation of hydroxymethylpyrimidine phosphate (HMP-P) to HMP-PP, and also probably that of HMP to HMP-P.1 Publication

Catalytic activityi

ATP + 4-amino-5-hydroxymethyl-2-methylpyrimidine = ADP + 4-amino-2-methyl-5-(phosphomethyl)pyrimidine.Curated
ATP + 4-amino-2-methyl-5-(phosphooxymethyl)pyrimidine = ADP + 4-amino-2-methyl-5-(diphosphooxymethyl)pyrimidine.Curated

Pathwayi: thiamine diphosphate biosynthesis

This protein is involved in step 2 and 3 of the subpathway that synthesizes 4-amino-2-methyl-5-diphosphomethylpyrimidine from 5-amino-1-(5-phospho-D-ribosyl)imidazole.
Proteins known to be involved in the 3 steps of the subpathway in this organism are:
  1. no protein annotated in this organism
  2. Hydroxymethylpyrimidine/phosphomethylpyrimidine kinase THI21 (THI21), Hydroxymethylpyrimidine/phosphomethylpyrimidine kinase THI20 (THI20)
  3. Hydroxymethylpyrimidine/phosphomethylpyrimidine kinase THI21 (THI21), Hydroxymethylpyrimidine/phosphomethylpyrimidine kinase THI20 (THI20)
This subpathway is part of the pathway thiamine diphosphate biosynthesis, which is itself part of Cofactor biosynthesis.
View all proteins of this organism that are known to be involved in the subpathway that synthesizes 4-amino-2-methyl-5-diphosphomethylpyrimidine from 5-amino-1-(5-phospho-D-ribosyl)imidazole, the pathway thiamine diphosphate biosynthesis and in Cofactor biosynthesis.

Links to similar proteins from the UniProt Reference Clusters (UniRef) at 100%, 90% and 50% sequence identity:
100%UniRef100 combines identical sequences and sub-fragments with 11 or more residues from any organism into one UniRef entry.
90%UniRef90 is built by clustering UniRef100 sequences that have at least 90% sequence identity to, and 80% overlap with, the longest sequence (a.k.a seed sequence).
50%UniRef50 is built by clustering UniRef90 seed sequences that have at least 50% sequence identity to, and 80% overlap with, the longest sequence in the cluster.
