Protein attributes

Sequence length	272 AA.
Sequence status	Complete.
Protein existence	Evidence at protein level

General annotation (Comments)

Function	Catalyzes the hydrolysis of 4-amino-2-methyl-5-hydroxymethylpyrimidine pyrophosphate (HMP-PP) to 4-amino-2-methyl-5-hydroxymethylpyrimidine phosphate (HMP-P). Can also hydrolyze other substrates such as MeO-HMP-PP and CF(3)-HMP-PP. Ref.6
Sequence similarities	Belongs to the HAD-like hydrolase superfamily. Cof family.
Sequence caution	The sequence AAB40202.1 differs from that shown. Reason: Erroneous initiation. Translation N-terminally shortened. The sequence CAA91181.1 differs from that shown. Reason: Erroneous initiation. Translation N-terminally shortened.
