WebMutants resistant to nikkomycin, an inhibitor of chitin biosynthesis, were isolated after exposure of wild-type spores of the fungus Phycomyces blakesleeanus to N-methyl-N′-nitro-N-nitrosoguanidine. Genetic analysis revealed that nikkomycin resistance was due to mutations in a single gene, chsA.

WebNov 1, 2006 · Convinced that chitin synthetase was a plasma membrane-bound enzyme, they regarded chitosomes as artefacts of cell disruption. This initial rejection of the chitosome concept seemed strange, particularly as a microvesicle-bound enzyme provided a much-needed vehicle for delivering chitin synthetase to the plasma membrane/cell … WebChitin was discovered by Henri Braconnot in 1811.
