Homology modeling of glycosyl hydrolase family 18 enzymes and proteins.

Using state-of-the-art homology modeling methods, three-dimensional coordinates for three family 18 glycosyl hydrolases were determined. The structures for Gp39, Brp39, and chitotriosidase were computer determined using the X-ray coordinates from SmChiA. The results of the modeling efforts are assessed, and comparison of the modeled structures to other known family 18 members is made.
