A novel post-translational modification of threonine, β-N-acetylglucosaminyl-phosphate, was recently discovered on assembly protein AP180, a protein which plays a crucial role in clathrin coated vesicle formation in synaptic vesicle endocytosis (SVE). Herein, we report studies aimed at probing the effect

The bacterial glmS ribozyme is mechanistically unique among both riboswitches and RNA catalysts. Its self-cleavage activity is the basis of riboswitch regulation of glucosamine-6-phosphate (GlcN6P) production, and catalysis requires GlcN6P as a coenzyme. Previous work has shown that the coenzyme

Glucosamine-6-phosphate synthase (GlmS) is responsible for the first and rate-limiting step in the hexosamine biosynthetic pathway. It catalyzes the conversion of D-fructose-6P (F6P) into D-glucosamine-6P (GlcN6P) using L-glutamine (Gln) as nitrogen donor (synthase activity) according to an ordered bi-bi process

The glmS-riboswitch is unique among riboswitch families as it represents a metabolite-dependent ribozyme that undergoes self-cleavage upon recognition of glucosamin-6-phosphate. The glmS-riboswitch is located in the 5'-untranslated region of bacterial genes involved in cell wall biosynthesis. Therefore, this riboswitch represents

The glmS ribozyme is the first naturally occurring catalytic RNA that relies on an exogenous, nonnucleotide cofactor for reactivity. From a biochemical perspective, the glmS ribozyme derived from Bacillus anthracis is the best characterized. However, much of the structural work

RNA is ideally suited for in vitro evolution experiments, because a single RNA molecule possesses both genotypic (replicable sequence) and phenotypic (selectable shape) properties. Using systematic evolution of ligands by exponential enrichment (SELEX), we found a single 58-nt aptamer sequence

Self-cleaving glmS ribozymes selectively bind glucosamine-6-phosphate (GlcN6P) and use this metabolite as a cofactor to promote self-cleavage by internal phosphoester transfer. Representatives of the glmS ribozyme class are found in Gram-positive bacteria where they reside in the 5' untranslated regions

We have synthesized a light-activatable ("caged") derivative of glucosamine-6-phosphate (GlcN6P), which only upon irradiation becomes a cofactor for the glmS riboswitch. This glmS riboswitch maintains its activity when embedded in the 3'-untranslated region of eukaryotic mRNA molecules and caged GlcN6P

Glucosamine-6-phosphate (GlcN6P) N-acetyltransferase 1 (GNA1) is a key enzyme in the pathway toward biosynthesis of UDP-N-acetylglucosamine, an important donor substrate for N-linked glycosylation. GNA1 catalyzes the formation of N-acetylglucosamine-6-phosphate (GlcNAc6P) from acetyl-CoA (AcCoA) and the acceptor substrate GlcN6P. Here, we

β-arrestin-2, a multifunctional adaptor protein, was originally identified as a negative regulator of G protein-mediated signaling. We previously revealed that SUMOylation as a novel mechanism modulates β-arrestin-2-mediated IL-1R/TRAF6 signaling. However, the potential role of β-arrestin-2 SUMOylation in tumor cells was

The role of adrenal hexose-6-phosphate dehydrogenase in providing reducing equivalents to P450 cytochrome steroidogenic enzymes in the endoplasmic reticulum is uncertain. Hexose-6-phosphate dehydrogenase resides in the endoplasmic reticulum lumen and co-localizes with the bidirectional enzyme 11β-hydroxysteroid dehydrogenase 1. Hexose-6-phosphate dehydrogenase

The glmS ribozyme-riboswitch is the first known example of a naturally occurring catalytic RNA that employs a small molecule as a coenzyme. Binding of glucosamine-6-phosphate (GlcN6P) activates self-cleavage of the bacterial ribozyme, which is part of the mRNA encoding the

The glmS riboswitch regulates gene expression through a self-cleavage activity. The reaction is catalyzed with the assistance of the metabolite cofactor glucosamine-6-phosphate (GlcN6P), whose amino group is proposed to serve as the general acid during the reaction. This reaction is

Uniquely among known ribozymes, the glmS ribozyme-riboswitch requires a small-molecule coenzyme, glucosamine-6-phosphate (GlcN6P). Although consistent with its gene-regulatory function, the use of GlcN6P is unexpected because all of the other characterized self-cleaving ribozymes use RNA functional groups or divalent cations

The glmS ribozyme is a conserved riboswitch found in numerous Gram-positive bacteria and responds to the cellular concentrations of glucosamine 6-phosphate (GlcN6P). GlcN6P binding promotes site-specific self-cleavage in the 5' UTR of the glmS mRNA, resulting in downregulation of gene

N-Acetylglucosamine-6-phosphate deacetylase (NagA) and glucosamine-6-phosphate deaminase (NagB) are branch point enzymes that direct amino sugars into different pathways. For Staphylococcus aureus NagA, analytical ultracentrifugation and small-angle X-ray scattering data demonstrate that it is an asymmetric dimer in solution. Initial rate experiments
