Abstract
An asporogenous strain of Bacillus subtilis, IS53, transformed with pl asmid pPA102, produces the protective antigen (PA) component of the tr ipartite toxin of B. anthracis. Addition of yeast extract was required to support growth and PA production in all the media examined. Protec tive antigen expression was down-regulated during exponential growth a nd extracellular proteases caused marked degradation of the mature pro tein.
