Point mutations in a peptidoglycan biosynthesis gene cause competence induction in Haemophilus influenzae.

abstract：:Bacillus subtilis, which grows under aerobic conditions, employs fatty acid desaturase (Des) to fluidize its membrane when subjected to temperature downshift. Des requires molecular oxygen for its activity, and its expression is regulated by DesK-DesR, a two-component system. Transcription of des is induced by the tem...
