Strep mutans survive without SRP (signal-recognition pathway)

Bacteria That Cause Tooth Decay Able To Survive Without Important Biochemical Pathway: "Scientists have long believed a certain biochemical pathway involved in the folding and delivery of proteins to cell membranes is essential for survival. Now University of Florida researchers have discovered that Streptococcus mutans, the decay-causing organism that thrives in many a mouth, can do just fine without it."
