ABSTRACT
Agarwal SM, Raghav D, Kumar
A, Predicted 3D structure, active site and ligand
docking of serine acetyltransferase, a drug target
for Entamoeba histolytica
Online J Bioinformatics. 11 (2): 264-281, 2010. Serine acetyltransferase
(SATase) is part of the biosynthetic pathway of E. histolytica,
an enteric parasite that causes amoebic colitis. The end product, cysteine is an important metabolite for the survival of E. Histolitica, thus SATase has
become a target for drug development. A 3D-homology model of EhSATase, active site and predicted interactions between
the protein and cysteine, the natural inhibitor are
described herein. EhSATase was characterized by unique
insertions in an a-helical conformation and an extended loop
between b-strand 7 and 8, giving rise to potential significant
structural differences. This structure knowledge may be useful for designing ehSATase inhibitors.
