The gerW protein Is not involved in the germination of spores of bacillus species
Germination of dormant spores of Bacillus species is initiated when nutrient germinants bind to germinant receptors in spores' inner membrane and this interaction triggers the reléase of dipicolinic acid and cations from the spore core and their replacement by water. Bacillus subtilis spores co...

| Resumo: | Germination of dormant spores of Bacillus species is initiated when nutrient germinants bind to germinant receptors in spores' inner membrane and this interaction triggers the reléase of dipicolinic acid and cations from the spore core and their replacement by water. Bacillus subtilis spores contain three functional germinant receptors encoded by the gerA, gerB, and gerK operons. The GerA germinant receptor alone triggers germination with L-valine or L-alanine, and the GerB and GerK germinant receptors together trigger germination with a mixture of L-asparagine, D-glucose, D-fructose and KCl (AGFK). Recently, it was reportedthat the B. subtilis gerW gene is expressed only during sporulation in developing spores, and that GerW is essential for L-alanine germination of B. subtilis spores but not for germination with AGFK |
