Objective(s): Nucleus Raphe Magnus (NRM) that is involved in the regulation of body temperature contains nitric oxide (NO) synthase. Considering the effect of NO on skin blood flow control, in this study, we assessed its thermoregulatory role within the raphe magnus. Materials and Methods: To this end, tail blood flow of male Wistar rats was measured by laser doppler following the induction of ...
The extremely halophilic archaeon Natrialba aegyptiaca secretes the L-homo type of poly-g-glutamate (PGA) as an extremolyte. We examined the enzymes involved in glutamate metabolism and verified the presence of L-glutamate dehydrogenases, L-aspartate aminotransferase, and L-glutamate synthase. However, neither glutamate racemase nor D-amino acid aminotransferase activity was detected, suggestin...
Introduction: The bed nucleus stria terminalis (BST) is a part of the limbic system, which plays a role in regulation of heart beat and blood circulation. It was recently shown that microinjection of L-glutamate in the BST elicits cardiovascular depressive, but the role of glutamate receptor subtypes has not been investigated yet. In this study, the role of glutamate receptor subgroups in regul...
The functional assignment of enzymes that catalyze unknown chemical transformations is a difficult problem. The protein Pa5106 from Pseudomonas aeruginosa has been identified as a member of the amidohydrolase superfamily by a comprehensive amino acid sequence comparison with structurally authenticated members of this superfamily. The function of Pa5106 has been annotated as a probablechlorohydr...
TO THE EDITOR: Matsumoto et al. (3) have reported that the lactating rat mammary gland maintains a large transepithelial L-glutamate concentration gradient in favor of milk and provide a model for the production of free L-glutamate in milk. They suggest that L-leucine is the major source of milk L-glutamate; it is envisaged that L-leucine is transported across the basolateral membrane of mammar...
Na⁺-dependent high-affinity glutamate transporters have important roles in the maintenance of basal levels of glutamate and clearance of glutamate during synaptic transmission. Interestingly, several studies have shown that basal glutamate transport displays plasticity. Glutamate uptake increases in hippocampal slices during early long-term potentiation (E-LTP) and late long-term potentiation (...
The roots of many plant species are known to use inorganic nitrogen, in the form of , as a cue to initiate localized root proliferation within nutrient-rich patches of soil. We report here that, at micromolar concentrations and in a genotype-dependent manner, exogenous l-glutamate is also able to elicit complex changes in Arabidopsis root development. l-Glutamate is perceived specifically at th...
