Cis regulators

MLS or PMS resistance, usually induced by erythromycin or occasionally by oleandomycin, follows a negative cis regulation by attenuators. In the absence of erythromycin, for example, the mRNA required for ErmC, methyltransferase, is previously synthesized on a template of the ermC operon in an inactive conformation, which permits the initiation of efficient translation [57,58]. 

Stereospecific polymerisation of isoprene (2-methyl-butadiene-1,3) in the presence of cis-regulating catalytic Ziegler-Natta systems can be described by the following... 

From both the experimental and theoretical points of view, the most thoroughly studied catalytic systems are undoubtedly allylnickel(II) systems and monocyclopentadienyl titanium complexes. In the case of the nickel systems, chain growth proceeding by BD insertion into the allyl-transition metal bond was proven directly by NMR spectroscopy for both 1,4-trans- and 1,4-cis-regulating catalysts. In this case, the proposed mechanism for stereoregulation suggests that the cis-trans...

Extractions and Chemical Analyses of Amaranthus palmerl S. Wats (Amaranthaceae). The plant material for the chemical studies was supplied by Dr. R. M. Menges, USDA, Weslaco, TX. The air-dried aerial parts (518 g) were extracted at ambient temperature with petroleum ether (PE), dichloromethane (CI Clj) and methanol (MeOH) and the solvents were evaporated In vacuo providing 4.5 g, 4.7 g and 12.lg crude extracts, respectively. Samples of the crude extracts were tested by Dr. J. M. Bradow for germination regulation activity and the biological data are described in her paper.
