Unusual amino acids such as beta-methoxytyrosine (beta-MeOTyr), allo-threonine (allo-Thr) and allo-isoleucine (allo-Ile) were derivatized with N-alpha-(2,4-dinitro-5-fluorophenyl)-L-alaninamide(More)
All 4 diastereomeric possibilities for the 2,3-dihydroxy-2,6,8-trimethyldeca-(4Z,6E)-dienoic acid (Dhtda) residue, found in the cyclic depsipeptide natural products papuamides A-D and mirabamides(More)
In this study we explored the efficiency of the additive methyl-beta-cyclodextrin (M beta CD) to enhance the activity and enantioselectivity of the serine protease subtilisin Carlsberg in organic(More)
Colyophilization with methyl-beta-cyclodextrin activates subtilisin Carlsberg by more than 200-fold in organic solvents, though this is a short-lived effect. About 93% of the enzyme's high initial(More)
