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 ...
Cloning and characterization of tomato leaf senescence-related cDNAs
(Kluwer Academic Publishers; Springer Science+Business Media, 1997-03)
Senescence-related cDNA clones designated SENU1, 4, 5 (senescence up-regulated) and SEND32, 33, 34, 35 and 36 (senescence down-regulated) isolated from a tomato leaf cDNA library [9] were characterized. Southern analysis ...
Identification and localization of an immunoreactiveAMPA-type glutamate receptor subunit (GluR4) with respect to identified photoreceptor synapses in the outer plexiform layer of goldfish retina
(Kluwer Academic Publishers; Chapman and Hall ; Springer Science+Business Media, 1997-10)
L-glutamate, the main excitatory synaptic transmitter in the retina, is released from photoreceptors and evokes responses in second-order retinal neurons (horizontal, bipolar cells) which utilize both ionotropic and ...
Milk composition and lactational output in the greater spear-nosed bat, Phyllostomus hastatus
(Springer-Verlag; Springer-Verlag Berlin Heidelberg, 1997-07)
Growth rates of mammalian young are closely linked to the ability of the mother to provide nutrients; thus, milk composition and yield provide a direct measure of maternal investment during lactation in many mammals. We ...
Steroid hormone responsiveness of a family of closely related mouse proviral elements
(Springer-Verlag; Springer-Verlag New York Inc., 1997-11)
Regulation of the mouse sex-limited protein ( Slp ) gene is unusual in that hormone response is conferred by the 5′ LTR of an upstream inserted provirus, dubbed the imposon ( imp1 ). In a search for additional genes whose ...
Transmission of mitochondrial DNA - playing favorites?
(Wiley Subscription Services, Inc., A Wiley Company, 1997-09)
Mitochondria are essential subcellular organelles containing an extranuclear genome (mtDNA). Mutations in mtDNA have recently been identified as causing a variety of human hereditary diseases. In most of these cases, the ...
Mutation watch:PEX PLUS? Gene(s) for X-linked hypophosphatemia and deafness
(Springer-Verlag; Springer-Verlag New York Inc., 1997-08)
Characterization of two cDNA clones for mRNAs expressed during ripening of melon (Cucumis melo L.) fruits
(Kluwer Academic Publishers; Springer Science+Business Media, 1997-01)
In vitro translation of mRNAs and polyacrylamide gel electrophoresis of proteins from melons revealed that several mRNAs increased in amount during ripening, indicating the existence of other ripening genes in addition to ...
Presynaptic terminals in hyaline cells of normal and overstimulated chick inner ears
(Kluwer Academic Publishers; Chapman and Hall ; Springer Science+Business Media, 1997-03)
Hyaline cells are non-sensory epithelial cells of the vibrating part of the basilar membrane of chicks; they receive an extensive efferent innervation. Although these anatomical features suggest roles in auditory transduction, ...
Application of membrane-based preferential transport to whole broth processing
(Wiley Subscription Services, Inc., A Wiley Company, 1997-08-20)
Preferential transport in adsorptive membranes can be used to selectively remove biochemicals directly from fermentation broths. During preferential transport, an adsorbing solute is selectively transported across the ...
