TOPOISOMERASE RESIDUES 410-1202,
Overview
The crystal structure of a large fragment of yeast type II DNA topoisomerase reveals a heart-shaped dimeric protein with a large central hole. It provides a molecular model of the enzyme as an ATP-modulated clamp with two sets of jaws at opposite ends, connected by multiple joints. An enzyme with bound DNA can admit a second DNA duplex through one set of jaws, transport it through the cleaved first duplex, and expel it through the other set of jaws.
About this Structure
1BGW is a Single protein structure of sequence from Saccharomyces cerevisiae. The following page contains interesting information on the relation of 1BGW with [Topoisomerases]. Full crystallographic information is available from OCA.
