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.
