Organism
M306I
hydroxylation reaction of deacetoxycephalosporin C, EC 1.14.11.26, is abolished, 59% of wild-type ring expansion activity
Acremonium chrysogenum
additional information
truncation of C-terminus to residue 310, 2fold enhancement of ring expansion reaction of penicillin G. Double mutant with truncation at residue 310 and M306I, selective catalyzation of ring expansion. Triple mutant with truncation at residue 310, M306I and N305L, selective catalization of ring expansion with improved kinetic parameters
Acremonium chrysogenum
N305L
107% of wild-type ring expansion activity, 85% of wild-type hydroxylation activity
Acremonium chrysogenum
W82A
5.5% of wild-type ring expansion activity, 71% of wild-type hydroxylation activity; ring expansion reaction of EC 1.14.20.1 is reduced
