The present invention relates to a bioadhesive derived from mussel. In particular, it relates to a novel Mytilus galloprovincialis foot protein type 5 (MGFP-5) and a recombinant protein that is a hybrid of MGFP-5 and foot protein type 1 (FP-1), where an adhesive protein with adhesive activity can be economically mass-produced to be used in place of chemical adhesives through the present invention.
