| Description |
Bacteriophage lambda C1 repressor controls the expression of viral genes as part of the lysogeny/lytic growth switch. C1 is essential for maintaining lysogeny, where the phage replicates non-disruptively along with the host. If the host cell is threatened, then lytic growth is induced. The Lambda C1 repressor consists of two domains connected by a linker: an N-terminal DNA-binding domain that also mediates interactions with RNA polymerase, and a C-terminal dimerisation domain. This type of viral DNA binding domain is also presents some eukaryotic proteins.
