Streptococcus thermophilus cell wall-anchored proteinase: release, purification, and biochemical and genetic characterization
Article Abstract:
The properties of the PrtS proteinase from Streptococcus thermophilus are described. The enzyme is a member of the subtilase family and is tightly bound to the cell wall. It is similar to cell envelope proteinases from pyogenic streptococci and lactic acid bacteria.

Expression of sex peptidases from Lactobacillus helveticus in Lactococcus lactis
Article Abstract:
Researchers introduced the genes for six peptidases from Lactobacillus helveticus into Lactococcus lactis. Aminopeptidase was produced in greater quantities than the other peptidases but the amount of some peptidases could be increased by putting them under the control of the inducible lactococcal nisA promoter.

Proteome analysis of Streptococcus thermophilus grown in milk reveals pyruvate formate-lyase as the major upregulated protein
Article Abstract:
The adaptation of Streptococcus thermophilus LMG18311 to milk is investigated using a protemic approach. The results have shown a novel regulatory mechanism controlling the synthesis of pyruvate formate-lyase (PFL) and have also suggested an unrecognized physiological role for PFL as a formate supplier for anabolic purposes.
