== Publication Abstract from PubMed ==
 +
We survey the two-state to downhill folding transition by examining 20 lambda(6-85)* mutants that cover a wide range of stabilities and folding rates. We investigated four new lambda(6-85)* mutants designed to fold especially rapidly. Two were engineered using the core remodeling of Lim and Sauer, and two were engineered using Ferreiro et al.'s frustratometer. These proteins have probe-dependent melting temperatures as high as 80 degrees C and exhibit a fast molecular phase with the characteristic temperature dependence of the amplitude expected for downhill folding. The survey reveals a correlation between melting temperature and downhill folding previously observed for the beta-sheet protein WW domain. A simple model explains this correlation and predicts the melting temperature at which downhill folding becomes possible. An X-ray crystal structure with a 1.64-A resolution of a fast-folding mutant fragment shows regions of enhanced rigidity compared to the full wild-type protein.

[[http://www.uniprot.org/uniprot/RPC1_LAMBD RPC1_LAMBD]] Repressor protein CI allows phage lambda to reside inactively in the chromosome of its host bacterium. This lysogenic state is maintained by binding of regulatory protein CI to the OR and OL operators, preventing transcription of proteins necessary for lytic development.
