(1) Structure assignment of the isomeric immonium ions 5 and 6, generated via FAB from N-isobutyl glycine and N-methyl valine, can be achieved by their collision induced dissociation characteristics.
(2) A broad specificity of LipDH was observed for the glycine cleavage system.
(3) Furthermore, in induced Friend cells 100 microM Fe-SIH stimulated 2-14C-glycine incorporation into heme up to 3.6-fold as compared to the incorporation observed with saturating concentrations of Fe-Tf.
(4) The property of melittin pores is shown to be provided by the amino group of the N-terminal glycine residue.
(5) 1H-NMR spectra of urine from a patient with propionic acidemia show peaks of 3-hydroxy-n-valerate, methylcitrate, propionyl glycine, 3-hydroxy-n-butyrate, lactate, 3-hydroxypropionate, tiglylglycine and hippurate.
(6) Thus acidic amino acids strongly inhibit acceptor activity as do glycine and proline residues as amino-terminal and carboxy-terminal neighbours, respectively.
(7) A significant proportion of the soluble protein of the organic matrix of mollusk shells is composed of a repeating sequence of aspartic acid separated by either glycine or serine.
(8) Serine (12.0-18.2%), tyrosine (5.8-9.0%) and glycine (4.5-7.1%), along with arginine, make up the bulk of the amino acid residues in these molecules.
(9) Substitution of a single amino acid residue, proline for glycine-9 in [pGlu6]SP6-11, a hexapeptide analogue of substance P, confers on the peptide selective agonist activity toward the SP-P receptor subtype.
(10) This pattern of labelling was enhanced by preincubation in 1.0 mM glycine but not affected by pre-incubation in 3.0 mM N-methyl-D-aspartate (NMDA).
(11) Other amino acids (glutamine, taurine, asparagine, alanine, serine) were only altered in single brain regions, or were not altered at all (aspartate, glycine, threonine, arginine).
(12) Forphenicinol, L-2-(4-formyl-3-hydroxymethylphenyl) glycine, is a newly discovered low molecular weight immunomodifier.
(13) For dipeptides containing the amino terminal residues glycine, alanine and phenylalanine, abstraction of the hydrogen from the carbon adjacent to the peptide nitrogen was the major process leading to the spin-adducts.
(14) The uptake of acetyl-L-carnitine was not strictly substrate-specific; gamma-butyrobetaine, L-carnitine, L-DABA, and GABA were potent inhibitors, hypotaurine and L-glutamate were moderate inhibitors, and glycine and beta-alanine were only weakly inhibitory.
(15) Pancreastatin is a 49 amino acid peptide with a C-terminal glycine amide originally isolated from porcine pancreas.
(16) Applications are presented for tripeptides of alanine and glycine in water.
(17) We have developed a sensitive radiochemical assay of glycine N-acyltransferase activity, using phenylacetyl-CoA as the acyl donor and glycine as the acceptor.
(18) The transport of arginine, aspartic acid, glycine, histidine, and threonine is not altered in the brnQ mutant under conditions in which that of the branched amino acids is.
(19) The study of the drugs effective in the treatment of cognitive deficits and memory loss associated with senile dementia of the Alzheimer's type--tacrine and amiridin, acetylcholinesterase inhibitor physostigmine and nootrop piracetam on uptake of 3H-serotonin (3H-5-HT), 3H-adrenaline (3H-AD), 3H-noradrenaline (3H-HA), 2H-dopamine (3H-DA), 3H-gamma-aminobutyric acid (3H-GABA), 3H-glutamic acid (3H-GLU), 3H-aspartic acid (3H-ASP) and 3H-glycine (3H-GLI) showed that tacrine and amiridin (5 x 10(-5) M) statistically significantly (P less than 0.05) inhibited the uptake of 3H-DA and 3H-5-HT.
(20) Five of the intermediates are of the form N-(methyloxycarbonyl)-X-glycine-C(= S)S-papain, where X is L-phenyl-alanine, D-phenylalanine, glycine, L-phenylglycine, or D-phenylglycine.
