Template-induced kinetic trapping of specific cyclodextrins in enzyme-mediated dynamic combinatorial libraries linear and cyclic α-glucans enables the one-step synthesis from maltose water.

Rational protein design is an emerging approach for testing general theories of structure and function. The ability to manipulate function rationally also offers the possibility of creating new proteins of biotechnological value. Here we use the design approach to test the current understanding of the structural principles of allosteric interactions in proteins and demonstrate how a simple allo...

Maltose binding protein (MBP) is widely used as a model for protein folding and export studies. We show here that macroscopic aggregates form transiently during the refolding of MBP at micromolar protein concentrations. Disaggregation occurs spontaneously without any aid, and the refolded material has structure and activity identical to those of the native, nondenatured protein. A considerable ...

In maltose syrup production, one of the critical processing stages is starch conversion process. During this process, reaction time and enzyme concentrations are two important parameters to obtain standard sugar spectrum. The purpose study is; i) find optimum during ii) determine process control dynamic in production. different amounts beta alpha-amylase enzymes (0.10, 0.15, 0.20 0.25 ml β-amyl...

Synthetic cellular logic gates are primarily built from gene circuits owing to their inherent modularity. Single proteins can also possess logic gate functions and offer the potential to be simpler, quicker, and less dependent on cellular resources than gene circuits. However, the design of protein logic gates that are modular and integrate with other cellular components is a considerable chall...

The Saccharomyces cerevisiae maltose transporter is a 12-transmembrane segment protein that under certain physiological conditions is degraded in the vacuole after internalization by endocytosis. Previous studies showed that endocytosis of this protein is dependent on the actin network, is independent of microtubules, and requires the binding of ubiquitin. In this work, we attempted to determin...
