Title : Alpha-galactosidase mutant D387A from Thermotoga maritima in complex with intact cyclohexene-based carbasugar mimic of galactose with 2,4-dinitro leaving group
Release Data : 2018-08-22
Compound :
mol_id molecule chains synonym
1 Alpha-galactosidase A Melibiase
ec: 3.2.1.22
other_details: Electron density at the N- and C-terminus was disordered and could not be modelled in the structure. Residue D387 was mutated to alanine in order to trap a complex with substrate.
