Phosphotransferase

In molecular biology, phosphotransferases are proteins in the transferase family of enzymes (EC number 2.7) that catalyze certain chemical reactions. The general form of the phosphorylation reactions they catalyze is:

$${\displaystyle {\ce {A-P + B <=> B-P + A}}}$$

Where P is a phosphate group and A and B are the donating and accepting molecules, respectively.
