Schematic representation of csmA disruption.
The N-terminal myosin motor-like domain and the C-terminal chitin
synthase domain are indicated by two hatched boxes. The relative
positions of deleted regions of csmA and of
‘chsD’ of Specht et al. (29) are shown with
marker genes. Abbreviations for representative endonucleases are as
follows: B, BamHI; Bg, BglII; S, SmaI;
St, StuI; X, XhoI.
