Dissociation and reconstitution of membranes synthesizing the peptidoglycan of Escherichia coli. Lipid dependence of the synthetic enzymes
A Taku, TM Hirsch and DP Fan
The peptidoglycan synthetic enzymes can be dissociated with cholate and
LiCl into components with mobilities on a gel filtration column in the same
ranges as bovine serum albumin. The active enzymes can be separated further
from the lipids necessary for synthesis by precipitation with ammonium
sulfate. The needed lipids stable to hydrolysis with base. A protein needed
for peptidoglycan polymerization can be separated from the other synthetic
enzymes by hydroxylapatite chromatography.
