Fig. 2From: Directed evolution of a genetically encoded immobilized lipase for the efficient production of biodiesel from waste cooking oilSchematic showing how PML could be accommodated in the Cry3Aa channel. a Dimensions of the PML fusion partner. b Structure of Cry3Aa [38]. Cry3Aa is an insecticidal protein used by Bacillus thuringiensis and contains three structural domains: a seven-helix bundle (Domain I), a three-sheet domain (Domain II), and a β sandwich (Domain III). c Cry3Aa self-assembles into protein crystals containing large solvent channels (50 Å by 50 Å)Back to article page
