Research

BACTERIAL DNA REPLICATION INITIATION

The Murray Lab studies bacterial DNA replication initiation in the model organism Bacillus subtilis. Using a combination of genetics, cell biology, molecular biology, and biochemistry, we are investigating the architecture of the bacterial chromosome origin, the essential activities of replication initiation proteins and the coordination of DNA synthesis with cell growth. One of the key tools we have developed is an inducible artificial chromosome origin that allows us to bypass normally essential endogenous replication initiation factors. We are keen to explore the utility of more sophisticated synthetic replication systems, both for fundamental understanding of DNA replication and for exploitation in biotechnology. We are also utilizing our expertise to search for novel antibiotics that target DNA replication proteins.
