Short lived bacterial regulatory proteins : what determines their fate?

Creator:

Ebel, Wolfgang, 1967-

Abstract:

Rapid degradation of certain short lived "timing" proteins is an effective mechanism for cells to control important regulatory pathways. The mechanisms by which regulatory proteases recognize their substrates are not well understood. Escherichia coli Lon, an energy dependent protease highly conserved in many prokaryotes and eukaryotes provides a model system...

Regulation of exopolysaccharide synthesis

Creator:

Dierksen, Karen P.

Abstract:

Lactococcus lactis subsp. cremoris Ropy 352 and L. lactis subsp. cremoris Hollandicus produce an exopolysaccharide (EPS) that imparts commercially desirable textural and rheological properties to fermented milk products. This ropy phenotype is expressed under specific environmental conditions. A mucoid EPS phenotype, also expressed under specific environmental conditions, but not involved...

The discriminator domain : does it reside at the C-terminus or the N-terminus of Escherichia coli Lon?

Creator:

Miller, Darcey L.

Abstract:

The mechanisms of substrate recognition by regulatory proteases are not well understood. Presently, two opposing models have arisen to describe E. coil Lon's ability to discriminate between substrates: one suggests the N-terminus involvement while the second suggests the C-terminus involvement. In this project, the role of the C-terminal domain as...
