Growth rate-dependent global effects on gene expression in bacteria.

abstract：:Staphylococcal enterotoxin B is known to be a powerful T cell stimulant in mouse and man. In this paper we show that, for mice, this is because the protein in association with major histocompatibility complex class II molecules stimulates virtually all T cells bearing V beta 3 and V beta 8.1, 8.2, and 8.3, and few oth...
