Purification and properties of an acid phosphatase of Micrococcus denitrificans distinct from thiamine phosphate phosphatase

J Biochem. 1977 Jul;82(1):307-9. doi: 10.1093/oxfordjournals.jbchem.a131686.


To determine whether the acid phosphatase in Micrococcus denitrificans participates in hydrolysis of thiamine phosphate in the synthesis of thiamine pyrophosphate, acid phosphatase was purified 280-fold by conventional procedures, which removed thiamine phosphate phosphatase completely. Studies showed that this acid phosphatase is a different protein from thiamine phosphate phosphatase and that it has no binding site for thiamine phosphate on its active site.
