Shalley Kudalkar
Shalley joined the Goodwin laboratory in June 2008. She has taken
up two projects. The first is to determine the role of the FG
interhelical insertion in giving catalase-peroxidases their striking
bifunctional capabilities. We have observed in the past that
removal of this entire loop leaves KatG peroxidase activity comparable
to wild type. However, there is little if any catalase
activity. The mechanism by which this structure specifically
supports catalase activity is not known. Shalley has produced a
series of KatG variants that are providing important insight into the
unique mechanism by which the insertion imparts catalase
activity. Shalley is also working on producing KatG proteins
amenable to x-ray structure determination.
