摘要

To determine the effect of the ionic environment on the marine adhesion moelcule Mytilus edulis foot protein 1 (Mefp-1),atomicforce microscopy (AFM)was used to measure the adhesion between Mefp-1 and a silica substrate under range of ionic conditions.Both ion strenght and type were varied on the basis of the basis of the ions present in natural seawater.Salts containing monovalentions (NaCl,KCl) increased adhesion only slightly,but salts containing divalentions (MgCl_2,CaCl_2,Na_2SO_4) induced multiple jump outs in the decompression curve similar to other biological systems and an increase in hydrodynamic radius as observed bylight scattering.This behavior may be due to metal complexation between 3,4-dihydroxyphenyl-L-alanine and o-qunione catechol groups on Mefp-1.The addition of a salt containing a trivalent ion (FeCl-3) resulted in the highest adhesion.The strong effectof salt type and concentration suggests that the ionic composition of the environment with in the mussel byssus may be tailored in order to achieve maximum adhesion and minimum curing time.
