Regulatory role of C-terminal residues of SulA in its degradation by Lon protease in Escherichia coli.

Abstract excerpt

The SulA protein is a cell division inhibitor in Escherichia coli, and is specifically degraded by Lon protease. To study the recognition site of SulA for Lon, we prepared a mutant SulA protein lacking the C-terminal 8 amino acid residues (SA8). This deletion protein was accumulated and stabilized more than native SulA in lon(+) cells in vivo. Moreover, the deletion SulA fused to maltose binding protein was not...
