After infection with bacteriophage T7 the beta' and to a lesser extent the beta subunits of E. coli DNA-dependent RNA polymerase (nucleosidetriphosphate:RNA nucleotidyltransferase, EC 2.7.7.6) are phosphorylated by a phage-gene-encoded protein kinase (ATP:protein phosphotransferase, EC 2.7.1.37). The phosphorylation occurs on threonine residues and appears site-specific. It is probably the molecular basis of the early transcriptional control.
用噬菌体T7感染后，大肠杆菌DNA依赖性RNA聚合酶（核苷三磷酸：RNA核苷酸基转移酶，EC 2.7.7.6）的β'亚基以及程度较轻的β亚基会被一种噬菌体基因编码的蛋白激酶（ATP：蛋白质磷酸转移酶，EC 2.7.1.37）磷酸化。磷酸化发生在苏氨酸残基上，且似乎具有位点特异性。它可能是早期转录调控的分子基础。
