Ten strains of Xanthomonas axonopodis pv. glycines, the causal agent of bacterial pustule of soybean, which were isolated from various soybean growing regions of Thailand, produced an extracellular diffusible factor (DSF) related to a well-characterized quorum sensing molecule produced by other Xanthomonas spp. Genomic DNA of the 10 strains of X. axonopodis pv. glycines contained rpfF, a gene e...

The genes encoding two different phospholipase C exoenzymes of Bacillus cereus are directly linked. A sequence comprising the gene for phospholipase C and part of the sphingomyelinase C (SMase) gene from strain SE-1 (1) as well as the entire SMase gene sequence from strain IAM 1208 (2) have recently been determined. We now report the complete sequence of the SMase gene from strain SE-1. Surpris...

C3 exoenzyme from Clostridium botulinum (C3bot1) ADP-ribosylates and thereby inactivates Rho A, B and C GTPases in mammalian cells. The structure of a tetragonal crystal form has been determined by molecular replacement and refined to 1.89 A resolution. It is very similar to the apo structures determined previously from two different monoclinic crystal forms. An objective reassessment of availa...
