Proteomic studies of growth and metabolism in Corynebacterium glutamicum R


EMSL Project ID
9800

Abstract

Corynebacterium glutamicum is a soil bacterium isolated in Japan in the 1950's as an L-glutamic acid producer (Kinoshita, et al., 1957). Strains derived from C. glutamicum are used in a number of industrial amino acid producing processes and recently, an annotated and complete genome sequence was published (Kalinowski et al., 2003). A group at the Research Institute of Innovative Technology for the Earth (RITE) has developed a process termed the "living-cell reaction" in which an isolate of C. glutamicum (termed Cornynebacterium glutamicum R) does not undergo cell division, but remains alive, secreting amino acids, organic acids or ethanol (depending on the strain used) with it's growth and metabolism effectively uncoupled (Terasawa, et al., 1989, 1990, 1991).

Using the living-cell reaction process we propose proteomic studies to characterize the interaction cell growth and metabolism pathways in C. glutamicum R. Initially, the proteome of C. glutamicum R maintained under various conditions (including the living-cell reaction conditions [growth suppressed conditions]) will be described and an Accurate Mass Tagged (AMT) database created. The AMT database will serve as a valuable tool for future proteomics studies.
