Self-assembling of chimeric mussel-inspired bio-adhesives originated from Mytilus californianus and Anabaena flos-aquae: A new approach to develop underwater adhesion
Source abstract
Abstract
Abstract Bio-adhesives play a pivotal role in a wide range of medical applications. However, there are some problems about their application in different pH values and low adhesion force under wet conditions. Here, we report new recombinant fusion protein achieved by mussel foot proteins (Mfps) of Mytilus Californianus and gas vesicle protein A (GvpA) of Anabaena flos-aquae by genetic engineering methods. Transmission electron microscopy verified that these chimeric proteins self-assembled into β-sheet rich fibres because of GvpA amyloid structure. Also, in comparison to other studies, their adhesion forces were significantly increased, especially in the alkaline environments based on Mfp-3 and Mfp-5, confirmed by the colloidal probe atomic force microscope. This study illustrates that copolymer of Mfp-5-GvpA:GvpA-Mfp-3 can be used as a sturdy underwater adhesive with tolerance to auto-oxidation, especially at basic conditions.
