1.14.99.53 Y56W mutation shows no detectable effect on substrate-binding preferences but, in synergy experiments with chitinases, the mutant appears to be more efficient on alpha-chitin -, 740434 1.14.99.53 additional information removal of the chitin-binding modules reduces LPMO activity toward alpha-chitin. The full-length enzyme and the individual catalytic LPMO module boost the activity of an endochitinase equally well 740758 1.14.99.53 Y54A mutation of residue at subsite -4, minimal effect on degradation of beta-chitin, about 20% residual activity with substrate [(1->4)-N-acetyl-beta-D-glucosaminyl]6 744375 1.14.99.53 A148G mutation leads to loss of C4 oxidation, i.e to the activity of EC 1.14.99.54 -, 745380 1.14.99.53 A148S mutation leads to loss of C4 oxidation, i.e to the activity of EC 1.14.99.54 -, 745380 1.14.99.53 D140A mutant shows moderately reduced activity and essentially unchanged oxidative regioselectivity -, 745380 1.14.99.53 additional information neither truncation of theLPMO10B family 2 carbohydrate-binding module nor mutations altering access to the solvent-exposed axial copper coordination site significantly change the C1:C4 oxidation ratio -, 745380 1.14.99.53 N85F mutation changes the C1:C4 oxidation ratio from 0.9 (for the wild-type) to 5.9 -, 745380 1.14.99.53 W82Y mutation changes the C1:C4 oxidation ratio from 0.9 (for the wild-type) to 2.0 -, 745380 1.14.99.53 W82Y/N85F mutation changes the C1:C4 oxidation ratio from 0.9 (for the wild-type) to 10.9 745380
