    Abstract: Disclosed is a method for promoting extracellular expression of proteins in B. subtilis using cutinase, which belongs to the technical fields of genetic engineering, enzyme engineering and microbial engineering. It teaches co-expressing a cutinase mutant and a target protein in B. subtilis to promote extracellular expression of the target protein which is naturally located inside cells. The target protein includes xylose isomerase, 4,6-α-glucosyltransferase, 4-α-glucosyltransferase, trehalose synthase, branching enzyme and the like. The invention can achieve extracellular expression of intracellularly localized target protein, improve the production efficiency, reduce the production cost and simplify the subsequent extraction process.

    Abstract: A method and system for providing a magnetic junction residing on a substrate and usable in a magnetic device are described. The magnetic junction includes a first pinned layer, a first nonmagnetic spacer layer having a first thickness, a free layer, a second nonmagnetic spacer layer having a second thickness greater than the first thickness, and a second pinned layer. The first nonmagnetic spacer layer resides between the pinned layer and the free layer. The first pinned layer resides between the free layer and the substrate. The second nonmagnetic spacer layer is between the free layer and the second pinned layer. Further, the magnetic junction is configured such that the free layer is switchable between a plurality of stable magnetic states when a write current is passed through the magnetic junction.

    Abstract: The present invention provides a method of increasing extracellular secretion of secretory proteins by co-expressing the secretory proteins with a mature cutinase. Cutinase can improve the permeability of E. coli cell membrane without destroying the membrane, and thus facilitate cross-membrane transfer of the secretory proteins co-expressed in E. coli. Increased extracellular secretion of target proteins can shorten cell culture time, reduce the formation of inclusion bodies and increase production of target proteins.
