Understanding the Plasticity of the α/β Hydrolase Fold: Lid Swapping on the Candida antarctica Lipase B Results in Chimeras with Interesting Biocatalytic Properties
Abstract The best of both worlds . Long molecular dynamics (MD) simulations of Candida antarctica lipase B (CALB) confirmed the function of helix α5 as a lid structure. Replacement of the helix with corresponding lid regions from CALB homologues from Neurospora crassa and Gibberella zeae resulted in...
