3-methyladenine Glcosylase II(AlkA) Hypoxanthine complex


Overview

Escherichia coli (E. coli) protein 3-methyladenine-DNA glycosylase II (AlkA) functions primarily by removing alkylation damage from duplex and single stranded DNA. A crystal structure of AlkA was refined to 2.0 A resolution. This structure in turn was used to refine an AlkA-hypoxanthine (substrate) complex structure to 2.4 A resolution. The complex structure shows hypoxanthine located in AlkA's active site stacked between residues W218 and Y239. The structural analysis of the AlkA and AlkA-hypoxanthine structures indicate that free hypoxanthine binding in the active site may inhibit glycosylase activity.

About this Structure

1PVS is a Single protein structure of sequence from Escherichia coli. Full crystallographic information is available from OCA.
