The ribosome-mediated, site-specific incorporation of unnatural amino acids into proteins is a powerful tool for creating protein analogues with specific steric, chemical, electronic or spectroscopic properties, in vitro and in vivo. The required aminoacyl ...
A simple three-step procedure converted the readily accessible (2-bromo-1,1-difluoroethyl)arenes into a-aryl-a,a-difluoroacetaldehydes. Subsequent hydrocyanation, hydrolysis, oxidn. and again hydrolysis afforded b-aryl-b,b-difluoro-a-oxopropionic acids. Re ...
The structure and the associated dynamics of a series of poly(?-benzyl-L-glutamate)-b-poly(dimethyl siloxane)-b-poly(?-benzyl-L-glutamate) (PBLG-b-PDMS-b-PBLG) triblock copolymers were investigated using small- and wide-angle X-ray scattering, NMR, transmi ...
The bioconversion of L-phenylalanine (L-Phe) to 2-phenylethanol (PEA) by the yeast Saccharomyces cerevisiae is limited by the toxicity of the product. PEA extn. by a sep. org. phase in the fermenter is the ideal in situ product recovery (ISPR) technique to ...
It is demonstrated here that three different alpha-amino N-carboxyanhydrides (NCAs), including for the first time O-benzyl-L-threonine NCA, can be polymerized in a controlled/"living" fashion without the need for transition metal catalysts or complex custo ...
This thesis deals with the supramolecular organization of chiral aminoacids and dipeptides on metal surfaces. The emergence of homochirality in biomolecular systems is one of the most intriguing open questions of Nature. The self-assembly and amplification ...
A novel in situ product removal (ISPR) method that uses microcapsules to ext. inhibitory products from the reaction suspension is introduced into fermn. technol. More specifically, L-phenylalanine (L-phe) was transformed by Saccharomyces cerevisiae to 2-ph ...
Molecular interactions of odorants with their olfactory receptors (ORs) are of central importance for the ability of the mammalian olfactory system to detect and discriminate a vast variety of odors with a limited set of receptors. How a particular OR bind ...
The inhibitory impacts of the bioconversion of L-phenylalanine (L-Phe) to 2-phenylethanol (PEA), a very important natural aroma compd., on the metab. of Saccharomyces cerevisiae Giv 2009 were investigated in batch and chemostat cultures. The bioconversion ...
An asym. synthesis of appropriately protected L-3-hydroxy-4-methoxy-5-Me phenylalanine from 3-methylcatechol is described featuring a key enantioselective alkylation step. [on SciFinder (R)] ...
