Induction of Chitin-Binding Proteins during the Specific Attachment of the Marine Bacterium Vibrio harveyi to Chitin

摘要: Previous work has shown that attachment of Vibrio harveyi to chitin is specific and involves at least two chitin-binding peptides. However, the roles regulation these peptides in are still unclear. Here we show preincubation with oligomeric sugars composing stimulated chitinase activity, cellular chitin, production One peptides, a 53-kDa peptide, produced constitutively appears mediate initial chitin. Synthesis another 150-kDa induced by thus may be involved time-dependent attachment. Coordinated degradation give bacteria like V. selective advantage over other nutrient-poor aquatic environments.
