site-directed mutagenesis, mutation of putative catalytic residue

site-directed mutagenesis, mutation of putative catalytic residue

-
site-directed mutagenesis, mutation of putative catalytic residue, mutant can only be stably expressed in Escherichia coli strain BL21(DE3) if altered to a soluble enzyme form dependent on IPTG induction
F295A
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. Mutant shows a much lower Ki (lauroyl-CoA) than wild-type
L276A/V277A
mutant shows significant decreased kcat values compared to wild-type
L276A/V277A/F295A
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
L291A
mutant shows kinetic behaviour relatively similar to wild-type toward substrates crotonyl-CoA and hexanoyl-CoA
Y240F
Y240F mutation leads to a 5000fold decrease in catalytic efficiency compared to wild-type with no significant change in Km
