β-Turns are ubiquitous in bioactive conformations of important peptides. We have designed a family of seven-membered lactam dipeptide mimics which are expected to act as conformational constraints in enforcing type VIa β-turns in peptide chains. Molecular modelling using Macromodel predicts that both 3(S)-acetylamino-7(S)-carboxy-azepan-2-one N-methyl amide (1, the cis-disubstituted lactam, MM2) and...
A 47 kDa integral peroxisomal membrane protein (PMP47) of Candida boidinii was expressed in wild type (WT) and a temperature-sensitive (Ts6) peroxisome-deficient (per) mutant of Hansenula polymorpha. The subcellular location of PMP47 appeared to be dependent on the level of expression. At low expression levels PMP47 was sorted to the peroxisomal membrane; however, in Ts6 cells grown at restrictive...
