University team synthesize seleno-insulin analog, retains physiological function and lasts longer
In a joint project, groups at Tokai University, Tohoku University and Osaka University have synthesized an insulin analog where one of the disulfide bonds linking the A- and B-chain is replaced by diselenide bonds („seleno-insulin“). X-ray analysis revealed a similar structure, but degradation in vitro by insulin-degrading enzyme IDE (a protease) was much slower (45 […]
