phosphotransferases

phos·pho·trans·fer·as·es

(fos'fō-trans'fĕr-ās-ĕz),
A subclass of transferases (EC subclass 2.7) transferring phosphorus-containing groups. Phosphotransferases include the "kinases" (2.7.1) transferring phosphate to alcohols, to carboxyl groups (2.7.2), to nitrogenous groups (2.7.3), or to another phosphate group (2.7.4). Phosphomutases (5.4.2) catalyze apparent intramolecular transfers; pyrophosphokinases (2.7.6) catalyze transfer of the pyrophosphate group; nucleotidyltransferases (2.7.7) catalyze transfer of the nucleotide (nucleotidyl) groups (including polyribonucleotide nucleotidyltransferase) and other similar groups (2.7.8).
Synonym(s): transphosphatases

The reason may be due to this fact that, in higher plants zinc is either required for, or at least modulates, the activity of a large number of various types of enzymes, including dehydrogenases, aldolases, isomerases and transphosphorylases.
