General Information

General Information Comment Organism
evolution three-quarters of the residues involved in interfacial regions are conserved, also the amino-acid residues in the nucleotide-binding, magnesium ion-binding and substrate-binding sites are conserved. The overall structure of PhThiK is similar to those of Bacillus subtilis ThiK (BsThiK) and Enterococcus faecalis V583 ThiK (EfThiK) Pyrococcus horikoshii
additional information the enzyme topology shows the typical ribokinase fold of an alpha/beta protein. Binding of the nucleotide and substrate to the ThiK enzyme do not influence the trimeric quaternary association Pyrococcus horikoshii
