A MUTATION WHICH CHANGES A MEMBRANE PROTEIN OF E. coli*
Abstract
A temperature-sensitive mutant of E. coli, which cannot synthesize DNA at high temperature but can continue cell division, shows a difference in a membrane protein fraction at high temperature by gel electrophoresis. This mutation of a bacterial membrane protein is unique. The protein may link DNA replication and cell division through the membrane.
