| Name: | 2-Methyl-4-amino-5-hydroxymethylpyrimidine diphosphate | ||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||
| Description | 2-methyl-4-amino-5-hydroxymethylpyrimidine diphosphate is a member of the chemical class known as Organic Pyrophosphates. These are organic compounds containing the pyrophosphate oxoanion, with the structure OP([O-])(=O)OP(O)([O-])=O. HMP-PP is involved in thiamin biosynthesis. Two redundant genes, THI20 and THI21, of Saccharomyces cerevisiae encode a 2-methyl-4-amino-5-hydroxymethylpyrimidine monophosphate (HMP-P) kinase required for thiamin biosynthesis. Although each isoform independently can synthesize HMP pyrophosphate (HMP-PP) from HMP, there is a marked difference in efficiency between the two proteins.
