Application

Phenolphthalein bisphosphate tetrasodium salt has been used as a component of modified Baird Parker (BP) agar to determine the expression of phosphatases of Staphylococcus aureus ATCC12600. It has also been used as a component of modified Tryptose phosphate/phenolphthalein/methyl green (M-TPMG) agar to detect enteroinvasive Escherichia coli (EIEC) apyrase activity.

Isocitrate dehydrogenase (IDH) gene from Staphylococcus aureus ATCC12600 was cloned, sequenced and characterized (HM067707). PknB site was observed in the active site of IDH; thus, it was predicted as IDH may be regulated by phosphorylation. Therefore, in this study, PknB
