Transpeptidase activity of Streptomyces D-alanyl-D carboxypeptidases.
In the presence of N(alpha),N(epsilon)-diacetyl-L-Lys-D-Ala-D-Ala as donor, and either D-[(14)C]alanine, [(14)C]-glycine, or meso-[(3)H]diaminopimelic acid as acceptor, the DD carboxypeptidases from Streptomyces R61 and R39 catalyze a transpeptidation reaction with the release of terminal D-alanine from the donor and the formation of either N(alpha),N(epsilon)-diacetyl-L-Lys-D-Ala-D-[(14)C]Ala,...
متن کاملSelective loss of alpha-melanotropin-amidating activity in primary cultures of rat intermediate pituitary cells.
The production of alpha-melanotropin (alpha-N-acetyl-ACTH(1-13)NH2 (alpha MSH) in rat intermediate pituitary was investigated using reverse phase high performance liquid chromatography, immunoassays, and biosynthetic labeling. Extracts of rat intermediate pituitary contain primarily alpha-N,O-diacetyl-ACTH(1-13)NH2, with smaller amounts of des- and monoacetyl-ACTH(1-13)NH2. No significant amoun...

In the mol-ecule of the title compound {systematic name: 3-[2-(6-hydr-oxy-5-hydroxy-methyl-5,8a-dimethyl-2-methyl-ene-per-hydro-1-napth-yl)-1-(nitro-meth-yl)eth-yl]-2(4H)-furan-one}, C(21)H(31)NO(6), the cyclo-hexane rings have chair conformations. Intra-molecular O-H⋯O hydrogen bonding results in the formation of a six-membered non-planar ring with a twist conformation. In the crystal structur...
متن کاملScreening of odor-receptor pairs in Caenorhabditis elegans reveals different receptors for high and low odor concentrations.
Olfactory systems sense and respond to various odorants. Olfactory receptors, which in most organisms are G protein (heterotrimeric guanine nucleotide-binding protein)-coupled receptors, directly bind volatile or soluble odorants. Compared to the genomes of mammals, the genome of the nematode Caenorhabditis elegans contains more putative olfactory receptor genes, suggesting that in nematodes th...
