MAP4, are phosphorylated by a cyclin-dependent kinase (CDK) that plays a major role in controlling the activities of proteins in the course of the cell cycle.

CII is a very unstable protein in E. coli; it is degraded by a specific protease called FtsH (HflB), encoded by the hfl gene.

N protein prevents termination in the early operons of lambda and it works together with the products of the bacterial genes nusA, nusB, nusE, and nusG.

N binds to RNA transcribed from DNA containing a nut sequence. Thus, once RNA polymerase has passed a nut site, N binds to the RNA and from there is loaded on to the polymerase itself. In this state, the polymerase is resistant to the terminators found just beyond the N and cro genes.
