The lambda and P22 phage repressors

J Biomol Struct Dyn. 1983 Dec;1(4):1011-22. doi: 10.1080/07391102.1983.10507499.

Abstract

The lambda cI repressor and the P22 c2 repressor contain two structural domains. In both proteins, the N-terminal domains mediate operator recognition and positive control of transcription, and the C-terminal domains mediate subunit oligomerization and recognition of the recA protein. In some cases, structural, biochemical, and genetic studies implicate particular repressor side chains in these processes.
