Bicolor

The ease of hydrolysis of a DMEU-treated fabric has been used to produce bicolored cotton fabrics. This was accompHshed by applying a thickened DMEU solution in a print configuration to the pile of fabric, curing the resin, and dyeing the fabric. The DMEU-treated areas resisted dyeing because of the cross-links. Subsequendy, the DMEU-crosslinks were removed via an acid hydrolysis and the entire fabric was overdyed to achieve the desired bicolored effect (69). 

More work has been done on the alkaloids of D. bicolor, Niitt, D. Menziesii, D.C., D. scopulorum, Gr. and D. Nelsonii, Gr. which, according to G. Heyl (1903), contain a mixture of alkaloids, having pharmacological properties akin to those of curare (Lohmann ) and hence named delpho-curarine. From this material he isolated a crystalline alkaloid, C23H33O7N, m.p. 184-5°, which contained methoxyl (18 per cent.).

The results for tree swallows (Tachycineta bicolor) in the area of the Upper Hudson River are surprising because the birds were still able to breed with TEQs far above the levels that had severe/fatal effects on other species of birds. However, there... 

Until 1987, the (R)-PaHNL from almonds was the only HNL used as catalyst in the enantioselective preparation of cyanohydrins. Therefore, it was of great interest to get access to HNLs which catalyze the formation of (5 )-cyanohydrins. (5 )-SbHNL [EC 4.1.2.11], isolated from Sorghum bicolor, was the first HNL used for the preparation of (5 )-cyanohydrins. Since the substrate range of SbHNL is limited to aromatic and heteroaromatic aldehydes as substrates, other enzymes with (5 )-cyanoglycosides have been investigated as catalysts for the synthesis of (5 )-cyanohydrins. The (5 )-HNLs from cassava (Manihot esculenta, MeHNL) and from Hevea brasiliensis (HbHNL) proved to be highly promising candidates for the preparation of (5 )-cyanohydrins. Both MeHNL and HbHNL have been overexpressed successfully in Escherichia coli, Saccharomyces cerevisiae and Pichia pastoris. 

The crystal structure of the HNL isolated from S. bicolor (SbHNL) was determined in a complex with the inhibitor benzoic acid." The folding pattern of SbHNL is similar to that of wheat serine carboxypeptidase (CP-WII)" and alcohol dehydrogenase." A unique two-amino acid deletion in SbHNL, however, is forcing the putative active site residues away from the hydrolase binding site toward a small hydrophobic cleft, thereby defining a completely different active site architecture where the triad of a carboxypeptidase is missing. 

Mechanisms of cyanogenesis have been published first based on the crystal structures of SbHNL from S. bicolor and of PaHNL from almonds." In this article, the mechanism of cyanogenesis will be discussed on the most proven mechanism of MeHNL from M. esculenta ...
