Crystallization (Commentary)

Crystallization (Comment) Organism
in complex with inhibitors 4-[2-(anthracen-9-ylmethylidene)hydrazino]-N-(3-chlorophenyl)-4-oxobutanamide, 4,4'-[cyclohexa-2,5-diene-1,4-diylidenebis[(E)methylylidene(E)diazene-2,1-diyl]]bis[N-(2-chlorophenyl)-4-oxobutanamide], and [(2E)-1-[4-[(2-chlorophenyl)amino]-4-oxobutanoyl]-2-(naphthalen-1-ylmethylidene)hydrazino]acetic acid. 4-[2-(Anthracen-9-ylmethylidene)hydrazino]-N-(3-chlorophenyl)-4-oxobutanamide binds at an enzyme monomer-monomer interface formed in the crystal of the complex, it sits at a central cleft between strands beta1 and beta4 of the beta sheet, which is the catalytic and substrate binding sites of the enzyme. The structures reveal a common binding site near residues Trp117, Try112, and Met109. This site overlaps but is distinct from the substrate-binding pocket Bacillus anthracis
