structures of CaTER in apo form at 2.1 A resolution, in complex with NADH at 2.0 A resolution and in complex with NAD+ at 2.7 A resolution
purified and crystallized as an apoenzyme and in a complex form with NADH and triclosan. The crystals of native and complexed FabI diffract to resolutions of 2.6 and 1.8 A, respectively. The crystals both belong to space group P2-1, with unit-cell parameters a = 117.32, b = 155.844, c = 129.448 A , beta = 111.061° for the native enzyme and a = 64.784, b = 107.573, c = 73.517 A, beta = 116.162° for the complex

mutant shows kinetic behaviour relatively similar to wild-type toward substrates crotonyl-CoA and hexanoyl-CoA
I287A
mutant shows significant decreased kcat values compared to wild-type, mutant exhibit larger increases in catalytic efficiency on the longer hexanoyl-CoA substrate (versus the crotonyl-CoA substrate) of 100 and 17fold compared to that of the wild type (7fold) suggesting suggest these mutations may increase the accessibility of the longer acyl chain to the active site pocket.
