Recombinant Spidroins Fully Replicate Primary Mechanical Properties of Natural Spider Silk - Biomacromolecules (ACS Publications)
So they got bacteria to build silk proteins with are almost twice as long as real spider silk proteins, thus the doubled protein is now a near match in performance to true spider silk fiber (true spider silk fiber benefits from good protein design and spinner design though). They seem to think it should be possible to use the fusing method to build even longer proteins to up the strength.
