Lactic acid bacteria (LAB) employ sucrase-type enzymes to convert sucrose into homopolysaccharides consisting of either glucosyl units (glucans) or fructosyl units (fructans). The enzymes involved are labeled glucansucrases (GS) and fructansucrases (FS), respectively. The available molecular, biochemical, and structural information on sucrase genes and enzymes from various LAB and their fructan...
Wide hybrids can have novel traits or changed expression of a quantitative trait that their parents do not have. These phenomena have long been noticed, yet the mechanisms are poorly understood. High-molecular-weight glutenin subunits (HMW-GS) are seed storage proteins encoded by Glu-1 genes that only express in endosperm in wheat and its related species. Novel HMW-GS compositions have been obs...
This review describes immunolocalization studies of the tissue and cellular location of glutamine synthetase (GS; EC 6.3.1.2) and glutamate synthase (Fd GOGAT; EC 1.4.7.1 and NADH-GOGAT; EC 1.4.1.14) proteins in roots and leaves of rice (Oryza sativa L.) and barley (Hordeum vulgare L.). In rice, cytosolic GS (GS1) protein was distributed homogeneously through all cells of the root. NADH GOGAT p...
Regulator of G Protein Signalling (RGS) proteins impede heterotrimeric G protein signalling. RGS2 decreases cAMP production and appears to interact with both adenylyl cyclase (AC) and its stimulatory G protein Gs. We showed previously that Green Fluorescent Protein-tagged RGS2 (GFP-RGS2) localizes to the nucleus in HEK 293 cells and is recruited to the plasma membrane when co-expressed with Gsa...
UNLABELLED In liver, most genes are expressed with a porto-central gradient. The transcription factor hepatic nuclear-factor4alpha (HNF4alpha) is associated with 12% of the genes in adult liver, but its involvement in zonation of gene expression has not been investigated. A putative HNF4alpha-response element in the upstream enhancer of glutamine synthetase (GS), an exclusively pericentral enzy...
Baloğlu E, Ke A, Abu-Taha IH, Bärtsch P, Mairbäurl H. In vitro hypoxia impairs 2-adrenergic receptor signaling in primary rat alveolar epithelial cells. Am J Physiol Lung Cell Mol Physiol 296: L500 –L509, 2009. First published December 19, 2008; doi:10.1152/ajplung.90390.2008.—Hypoxia inhibits 2-adrenergic receptor ( 2-AR) signaling in a variety of tissues, but effects in alveolar epithelium ar...
The protein content and its type are principal factors affecting wheat (Triticum aestivum) end product quality. Among the wheat proteins, glutenin proteins, especially, high molecular weight glutenin subunits (HMW-GS) are major determinants of processing quality. Wheat and its primary gene pool have limited variation in terms of HMW-GS alleles. Wild relatives of wheat are an important source of...
Aged beef cows (≥ 8 yr of age) produce calves with lower birth and weaning weights. In mammals, aging is associated with reduced hepatic expression of glutamine synthetase (GS) and alanine transaminase (ALT), thus impaired hepatic Gln-Glu cycle function. To determine if the relative protein content of GS, ALT, aspartate transaminase (AST), glutamate transporters (EAAC1, GLT-1), and their regula...
Between 1998 and 2011, the Venezuelan arachnologist Manuel Ángel González-Sponga (GS) published a series of taxonomic papers devoted to the Pholcidae of Venezuela. Of his 22 new genera, 20 were monotypic when described, suggesting a high percentage of synonyms. We studied his descriptions and as far as accessible his type specimens and propose the following new generic synonymies: Autana GS, 20...
Partially fed (4 -5 days) H .a. anatolicum (Iranian isolate) female adult ticks were used for preparation of antigens of midgut which are, the gut supernate antigen (GS), gut membrane antigen (GM), triton extracted gut membrane antigen ( TX-GM ) and sodium dodecyl sulphate treated Triton extracted gut membrane antigen (SDS-TX-GM). The New Zealand white rabbits were immunized with GS, GM, TX- ...
