(3) It resembled that of a bilane (tetrapyrrylmethane) but was different from that of a 2-(hydroxymethyl)bilane.
(4) Those who know Wogan say he had become disillusioned with the way the contest was heading, but that he also hadn't grasped the way it had changed with the entry of eastern European countries, with Russia's winner last year, Dima Bilan, hugely popular in former Soviet states.
(5) Russia is hosting the 2009 event on Saturday following the victory last year in Serbia of the mullet-haired Russian singer Dima Bilan.
(6) It is established that a single intramolecular rearrangement occurs and that this step comes at the end of the assembly of four porphobilinogen units which forms the unrearranged bilane.
(7) Russia is hosting the event following last year's victory in Serbia by the mullet-haired Russian singer Dima Bilan.
(8) The tetrapyrrole could only be partially displaced from the enzyme by ammonium ions, although a small amount of 2-(aminomethyl)bilane was always formed together with the tetrapyrrole intermediate.
(9) Uro'gen III formation from 2-(hydroxymethyl)bilane (HMB) and from the deaminase-tetrapyrrole intermediate was compared by using deaminase-cosynthase and cosynthase from several sources.
(10) The principal intermediate that accumulated was the correspondingly labeled (hydroxymethyl)bilane (HMB), the assignments for which are also presented.
Bilin
Definition:
(n.) A name applied to the amorphous or crystalline mass obtained from bile by the action of alcohol and ether. It is composed of a mixture of the sodium salts of the bile acids.
Example Sentences:
(1) These results indicate that an A-ring ethylidene-containing bilatriene is required for post-translational covalent attachment of bilin to apophytochrome and that apophytochrome may be the bilin C-S lyase which catalyzes bilin attachment.
(2) Some regions of the sequence are most similar to the retinol-binding protein, beta-lactoglobulin subgroup, while the disulphide bonding pattern is more akin to that seen in the porphyrin binding proteins insecticyanin and bilin-binding protein.
(3) Two of the free bilins were identified as 3(E)-phycocyanobilin and 3(E)-phycoerythrombilin by comparative spectrophotometry and high pressure liquid chromatography.
(4) Amino acid residues which might contact the bilin at each of the two variable sites were inferred by sequence alignment with phycocyanins.
(5) The evidence from the NMR data for all bilin peptides examined includes the dipoledipole interactions of the 5-H with the 3-H, 3'-H, and a pyrrole methyl group (7-CH3); the corresponding interactions would not be possible in a D-ring-linked bilin.
(6) Analysis of bilin peptides obtained upon tryptic digestion of the adduct showed residues alpha-Cys-84 and beta-Cys-82 to be the sites of bilin addition.
(7) delta-Aminolevulinic acid is the universal precursor for all tetrapyrroles including hemes, chlorophylls, and bilins.
(8) 6301 C-phycocyanin and the phycoerythrobilin-containing peptide beta-2TP from Porphyridium cruentum B-phycoerythrin indicated a different single thioether mode of attachment, postulated to be through the D-ring of the tetrapyrrole, in contrast to the A-ring linkage established for the other singly linked bilins in these proteins (Bishop, J.E., Lagarias, J.C., Nagy, J. O., Schoenleber, R.W., Rapoport, H., Klotz, A.V., and Glazer, A.N.
(9) Phycocyanobilin is the immediate precursor of the protein-bound bilin.
(10) Chromophore-containing peptides were produced by trypsin treatment and purified in order to isolate the individual peptide-bound bilins free of overlapping absorption.
(11) Immunophenotyping, however, showed extensive overlap of myeloid and lymphoid markers, confirming the leukemia to be biphenotypic rather than true "bilineal."
(12) Putative bilin-contacting residues differing between the two phycoerythrins were identified which may determine bilin specificity.
(13) However, these results imply that the information loss due to bilineality is not necessarily very great.
(14) The light-absorbing chromophores of the phycobiliproteins are linear tetrapyrroles (bilins) very similar in structure to the mammalian bile pigments.
(15) These measurements show that 62-75% of the phytochrome apoprotein in the soluble protein extract was competent to assemble with bilins to form spectrally active holophytochrome.
(16) In contrast, six bilins were attached to strain WH8103 and WH8020 PE(II)s. Five of these were at positions homologous to bilin attachment sites in other phycoerythrins.
(17) However, comparison of the bilins of Cr-PE 566 from strain Bermani with those of Cr-PE 566 of strain CBD shows that the two proteins carry different bilins on the alpha subunit.
(18) Two groups of ASP alcoholic patients were compared: (1) 11 high familial (bilineal) alcoholics, and (2) 22 low familial (nonfamilial or unilineal) alcoholics.
(19) Comparison of the bilin portion of the NMR spectra of the alpha-1 MBV and beta-1 MBV peptides to the NMR spectra of PCB and mesobiliverdin confirms that the bilin of the two adduct peptides resembles mesobiliverdin in having an extra double bond in the C2-C3 position of ring A.
(20) These results show that the major bilin products arising from the reaction of PCB with apophycocyanin differ from the bilins present in C-phycocyanin.
