The present disclosure relates to methods for producing recombinant proteins, as well as compositions used in and produced by such methods. Specifically, the present disclosure relates to methods for producing high secreted yields of recombinant proteins, and the compositions provided herein include expression constructs, recombinant vectors, and recombinant host cells that comprise polynucleotide sequences encoding proteins operably linked to recombinant secretion signals that comprise the leader peptide of the α-mating factor (αMF) ofand a non-αMF signal peptide.

Compositions and methods for producing high secreted yields of recombinant proteins

This invention relates to elastomeric protein and elastomeric protein production. In particular, the invention is directed to elastomeric protein sequences, including methods and compositions for production of elastomeric protein sequences, such as expression constructs, and host cells, and including compositions generated from the elastomeric protein sequences.

Elastomeric proteins

The present disclosure relates to methods for producing recombinant proteins, as well as compositions used in and produced by such methods. Specifically, the present disclosure relates to methods for producing high secreted yields of recombinant proteins, and the compositions provided herein include expression constructs, recombinant vectors, and recombinant host cells that comprise polynucleotide sequences encoding proteins operably linked to recombinant secretion signals that comprise the leader peptide of the &#x3b1;-mating factor (&#x3b1;MF) ofand a non-&#x3b1;MF signal peptide.

The present disclosure provides methods and compositions for directed to synthetic block copolymer proteins, expression constructs for their secretion, recombinant microorganisms for their production, and synthetic fibers (including advantageously, microfibers) comprising these proteins that recapitulate many properties of natural silk. The recombinant microorganisms can be used for the commercial production of silk-like fibers.

Methods and compositions for synthesizing improved silk fibers

The present disclosure provides improved long uniform recombinant protein fibers with desirable physical traits. The present disclosure also provides compositions derived from the long uniform recombinant protein fibers.
