Infrared Spectra of α- and γ-Glutamyl Dipeptides

Localization and characterization of γ-glutamyl cyclotransferase in cancer cells.

Using differential display analysis, we have identified a novel rat gene whose expression is increased during tumor progression in rat mammary carcinoma cell lines. This gene is an ortholog of the human chromosome 7 open reading frame 24 gene (C7orf24) and encodes a protein of 188 amino acids with no recognized protein domains. C7orf24 has been identified as γ-glutamyl cyclotransferase (GGCT), ...

Influx of two dipeptides, glycylsarcosine and L-glutamyl-L-glutamic acid, into hamster jejunum in vitro.

1. This paper reports an investigation of whether the dipeptides glycylsarcosine and L-glutamyl-Lglutamic acid share a single mediated transport mechanism into hamster jejunum, or whether one of these peptides is transported in part by a transport mechanism unavailable to the other. It describes the kinetics of influx of glycylsarcosine and of L-glutamyl-L-glutamic acid into rings of everted ha...

Transcriptome Profiling Identifies Candidate Genes Associated with the Accumulation of Distinct Sulfur γ-Glutamyl Dipeptides in Phaseolus vulgaris and Vigna mungo Seeds

Common bean (Phaseolus vulgaris) and black gram (Vigna mungo) accumulate γ-Glutamyl-S-methylcysteine and γ-Glutamyl-methionine in seed, respectively. Transcripts were profiled by 454 pyrosequencing data at a similar developmental stage coinciding with the beginning of the accumulation of these metabolites. Expressed sequence tags were assembled into Unigenes, which were assigned to specific gen...

Near-Infrared Spectra of Ultraluminous Infrared Galaxies.

Near-infrared spectra with a resolution of lambda&solm0;Deltalambda approximately 1100 in the rest-wavelength range of 1.8-2.2 µm have been obtained for a complete sample of 33 ultraluminous infrared galaxies (ULIRGs). Of the 33 objects observed, two show evidence of a central active galactic nucleus (AGN) through either a broad Paschen-alpha line or emission in the 1.963 µm fine structure of [...
