The sequence of the non-haemolytic enterotoxin operon from Bacillus cereus.
The non-haemolytic enterotoxin from Bacillus cereus has been sequenced. It is composed of three components, non-haemolytic enterotoxin A, B and C of 41.0, 39.8 and 36.5 kDa, respectively. Transcription of the operon seems to be positively regulated by plcR, a gene that also regulates phospholipase C expression. There is substantial similarity between the three proteins of non-haemolytic enterotoxin and between the non-haemolytic enterotoxin and haemolytic enterotoxin proteins.
