LYS(B28)PRO(B29)-HUMAN INSULIN

Overview

BACKGROUND: LysB28ProB29-human insulin (Humalog), a fully potent insulin, analog in which the prolyl, lysyl sequence at the C-terminal end of the, B-chain is inverted, exhibits a decreased association of monomers to, dimers leading to rapid in vivo absorption. This provides important, benefits for the insulin-requiring diabetic. In spite of its monomeric, nature, LysB28ProB29-human insulin can exist as a discrete hexameric, structure in the presence of both zinc and phenol. Studies of the crystal, structure of LysB28ProB29-human insulin in a hexameric complex were, initiated to gain a molecular understanding of the effect of the sequence, inversion on the analog's self-association properties and, consequently, its in vivo efficacy. RESULTS: Under the conditions reported, ... [(full description)]
