Crystallization (Commentary)

Crystallization (Comment) Organism
molecular dynamics simulation. In the apo-enzyme, the two catalytic residues are chemically equivalent and are expected to be both unprotonated. Upon substrate binding, the catalytic residues of HTLV-1 protease evolve to a singly protonated state, in which the carboxylic oxygen atom OD1 of Asp32 is protonated and forms a hydrogen bond with the OD1 atom of Asp32' , which is unprotonated Human T-cell leukemia virus type I
