Cysteine 265 Is in the Active Site of, But Is Not Essential for Catalysis by tRNA-Guanine Transglycosylase (TGT) from Escherichia coli
(Kluwer Academic Publishers-Plenum Publishers; Plenum Publishing Corporation ; Springer Science+Business Media, 1997-01)
Site-directed mutagenesis and X-ray absorption spectroscopy studies have previously shown that the tRNA-guanine transglycosylase (TGT) from Escherichia coli is a zinc metalloprotein and identified the enzymic ligands to ...
Optimal foraging and fitness in Columbian ground squirrels
(Springer-Verlag, 1990-01)
Optimal diets were determined for each of 109 individual Columbian ground squirrels ( Spermophilus columbianus ) at two sites in northwestern Montana. Body mass, daily activity time, and vegetation consumption rates for ...
Length variation of CAG repeats in Sry across populations of Mus domesticus
(Springer-Verlag, 1995-03)
The bicoid -related Pitx gene family in development
(Springer-Verlag; Springer-Verlag New York Inc., 1999-02)
Homologs of genes and anonymous loci on human Chromosome 13 map to mouse Chromosomes 8 and 14
(Springer-Verlag, 1995-04)
To enhance the comparative map for human Chromosome (Chr) 13, we identified clones for human genes and anonymous loci that cross-hybridized with their mouse homologs and then used linkage crosses for mapping. Of the clones ...
Protein tyrosine phosphatases in disease processes
(Elsevier, 1994-12)
Given the importance of tyrosine phosphorylation of proteins in signalling pathways, it is perhaps not surprising that protein tyrosine phosphatases (PTPs) are involved in the pathogenesis of certain human diseases. A PTP ...
Coupling of dihydroriboflavin oxidation to the formation of the higher valence states of hemeproteins
(Elsevier, 1991-11-27)
SummaryThe reactions between hydrogen peroxide and hemeproteins have been coupled to the oxidation of dihydroriboflavin so as to provide a simple method for measuring the rate constant of hemeprotein peroxidation. ...
A new 3D HN(CA)HA experiment for obtaining fingerprint H N -H α cross peaks in 15 N- and 13 C-labeled proteins
(Kluwer Academic Publishers; ESCOM Science Publishers B.V. ; Springer Science+Business Media, 1992-03)
A new 3D 1 H− 15 N− 13 C triple resonance experiment is presented that provides in-phase absorptive cross peaks between amide protons and α-protons of the same and the sequentially preceding residue. The experiment yields ...
Post-translational processing of gastrin in neoplastic human colonic tissues
(Elsevier, 1992-12-15)
Gastrin has been postulated to stimulate proliferation in colorectal neoplasms. Although gastrin mRNA has been demonstrated to be present in colon cancer cell lines, the intact peptide had not been recovered from human ...
