The international programme to sequence the 4.2 Mb genome of Bacillus
subtilis, a model Gram-positive bacterium, is a joint project involvin
g European, Japanese and US research groups. To date ca, 3.0 Mb of the
genome has been sequenced, with the remaining 1.2 Mb expected to be c
ompleted in 1997. The amenability of B. subtilis to genetic manipulati
on, combined with the availability of extensive expertise on its bioch
emistry and physiology, makes this bacterium a valuable organism in wh
ich to investigate the properties of genes for which functions cannot
be readily ascribed by standard methods.
