Active Site of Ribonucleoside Diphosphate Reductase from Escherichia coli
Ribonucleoside diphosphate reductase is an allosteric enzyme consisting of two nonidentical subunits, proteins Bl and B2. Bl contains dithiols which participate in the oxidation-reduction reactions of electron transport, while B2 contains a free radical essential for activity. Ribonucleoside diphosphates are bound to Bl but not to B2. Addition of 2’-deoxy-2’-chloro ribonucleoside diphosphates t...
متن کاملGenetic engineering of Escherichia coli to improve L-phenylalanine production
BACKGROUND L-phenylalanine (L-Phe) is an essential amino acid for mammals and applications expand into human health and nutritional products. In this study, a system level engineering was conducted to enhance L-Phe biosynthesis in Escherichia coli. RESULTS We inactivated the PTS system and recruited glucose uptake via combinatorial modulation of galP and glk to increase PEP supply in the Xllp...
متن کاملCrystal structure at 1.2 A resolution and active site mapping of Escherichia coli peptidyl-tRNA hydrolase.
Peptidyl-tRNA hydrolase activity from Escherichia coli ensures the recycling of peptidyl-tRNAs produced through abortion of translation. This activity, which is essential for cell viability, is carried out by a monomeric protein of 193 residues. The structure of crystalline peptidyl-tRNA hydrolase could be solved at 1.2 A resolution. It indicates a single alpha/beta globular domain built around...
متن کاملMetabolic engineering of Escherichia coli for production of 2‐Phenylethylacetate from L‐phenylalanine
In order to meet the need of consumer preferences for natural flavor compounds, microbial synthesis method has become a very attractive alternative to the chemical production. The 2-phenylethanol (2-PE) and its ester 2-phenylethylacetate (2-PEAc) are two extremely important flavor compounds with a rose-like odor. In recent years, Escherichia coli and yeast have been metabolically engineered to ...
متن کاملIn silico Study of Toll-Like Receptor 4 Binding Site of FimH from Uropathogenic Escherichia coli
Introduction : The innate immune system as the first line of defense against the pathogens recognizes pathogen-associated molecular patterns (PAMPs) by Toll-Like Receptors (TLRs). Interaction of bacterial PAMPs by TLRs results in activation of innate and acquired immunity. FimH adhesin, a minor component of type 1 fimbriae encoded by Uropathogenic Escherichia coli (UPEC) is a PAMP of TLR4 tha...
