Structure-function of cyanobacterial outer-membrane protein, Slr1270: Homolog ofEscherichia colidrug export/colicin import protein, TolC
2014
FEBS Letters
Compared to thylakoid and inner membrane proteins in cyanobacteria, no structure-function information is available presently for integral outer-membrane proteins (OMPs). The Slr1270 protein from the cyanobacterium Synechocystis 6803, over-expressed in Escherichia coli, was refolded, and characterized for molecular size, secondary structure, and ion-channel function. Refolded Slr1270 displays a single band in native-electrophoresis, has an a-helical content of 50-60%, as in E. coli TolC with
