Recombinant Human CMPK1 (His-Tag)

Recombinant Human CMPK1 (His-Tag) was expressed in E. coli and purified, which contains the full length of human CMPK1 (Pro2-Gly196) with His-Tag fusion at the N-terminus. CMPK1, also known as UMP-CMP kinase is part of the nucleotide metabolism network, which is responsible for the synthesis and interconversion of nucleotides that are essential for cellular activities. This enzymatic activity is of importance in the de novo biosynthesis of pyrimidine nucleotides, representing a critical step in the synthesis of essential cellular components. During this process, CMPK1 preferentially selects uridine monophosphate (UMP) and cytidine monophosphate (CMP) as phosphate receptors. Additionally, CMPK1 exhibits extensive nucleoside diphosphate kinase activity, demonstrating its versatility in catalyzing the transfer of phosphate groups between different nucleoside diphosphates. The multifaceted functions of CMPK1 reveal its pivotal role in cellular nucleotide metabolism and its potential impact on various cellular processes.

Recombinant Human NQO1 Protein

Recombinant Human NQO1 Protein (EC 1.6.99.2), namely Recombinant Human NAD(P)H Quinone Oxidoreductase 1 (NQO1), is also known as NAD(P)H:(quinone acceptor) oxidoreductase, DT-diaphorase, NADH-menadione reductase and other aliases. It is a homodimeric FAD-dependent flavoprotein. This product uses NADH or NADPH as electron donors to catalyze the two-electron reduction of quinones, nitroaromatic compounds, azo dyes and other substrates.

Thioredoxin Glutathione Reductase (smTGR)

Thioredoxin Glutathione Reductase (SmTGR), namely Schistosoma mansoni Thioredoxin Glutathione Reductase (SmTGR). Schistosoma mansoni lacks thioredoxin reductase and glutathione reductase. Thioredoxin glutathione reductase (TGR) possesses both thioredoxin reductase and glutathione reductase activities. This enzyme can reduce oxidized glutathione (GSSG) to reduced glutathione (GSH) in an NADPH-dependent manner; it is also capable of reducing thioredoxin (Trx) and 5,5'-dithiobis-(2-nitrobenzoic acid) (DTNB).

Human HMG-CoA Reductase

HMG-CoA reductase serves as the rate-limiting enzyme in cholesterol biosynthesis. Its activity is controlled by a negative feedback mechanism mediated by sterols and non-sterol metabolites derived from mevalonate, the catalytic product of this enzyme. In normal mammalian cells, this enzyme is inhibited by cholesterol obtained from the uptake and degradation of low-density lipoprotein (LDL) through LDL receptors. Competitive inhibitors targeting HMG-CoA reductase upregulate hepatic LDL receptor expression, thereby accelerating the breakdown of plasma LDL and reducing circulating cholesterol levels — a key risk factor for atherosclerosis. Alternatively spliced transcript variants of the HMGCR gene have been identified, encoding distinct protein isoforms.

Cytochrome P450 Reductase (human, recombinant)

Cytochrome P450 Reductase (human, recombinant) (EC 1.6.2.4), also referred to as Recombinant Human NADPH-cytochrome P450 Reductase or Recombinant Human NADPH-cytochrome P450 Oxidoreductase, is abbreviated as POR, rhPOR, P450R, rhP450R, CYPOR or CPR. Its Chinese names are Recombinant Human NADPH Cytochrome P450 Reductase and Recombinant Human NADPH Cytochrome P450 Oxidoreductase. Detailed information is provided below.

Recombinant E. coli Ethanolamine Ammonia-Lyase

Ethanolamine Ammonia-Lyase is an adenosylcobalamin (AdoCbl, i.e., Vitamin B12)-dependent enzyme that converts ethanolamine to acetaldehyde and ammonia. It exists in a variety of bacteria including Escherichia coli, Klebsiella aerogenes, Bacillus megaterium and Salmonella Typhimurium. This enzyme consists of the large α-subunit encoded by eutB and the small β-subunit encoded by eutC. EAL from Clostridium species and Salmonella Typhimurium adopts an α₆β₆ dodecameric architecture . EAL is the first enzyme in the ethanolamine catabolic pathway of bacteria harboring the ethanolamine utilization (eut) operon. In the presence of exogenous adenosylcobalamin, EAL is essential for bacterial growth in ethanolamine-rich environments. Numerous pathogens carrying eut genes contribute to foodborne illnesses; accordingly, inhibitors targeting the ethanolamine degradation pathway hold great research significance.

Recombinant Human B4GALT1 Protein (Y285L)

Recombinant Human B4GALT1 Protein (Y285L), also referred to as Recombinant Human β-1,4-Galactosyltransferase 1 (Y285L) or simply β-1,4-GalTase 1 Y285L, is a human extracellular catalytic domain of B4GALT1 (Globular catalytic domain, Leu126–Ser398) recombinantly expressed in E. coli. A point mutation substitutes tyrosine (Tyr, Y) at position 285 with leucine (Leu, L). The Y285L mutation remodels the conformation of the substrate-binding pocket, enabling the enzyme to specifically transfer N-azidoacetylgalactosamine (GalNAz) from UDP-N-azidoacetylgalactosamine (UDP-GalNAz) onto N-acetylglucosamine (GlcNAc) to generate non-reducing β1-4 linked GalNAz.

Recombinant Human B4GALT1 Protein (≥4 U/μg)

Recombinant Human B4GALT1 Protein (≥4 U/μg), also known as Recombinant Human β-1,4-Galactosyltransferase 1 (β-1,4-GalTase 1), is a highly active human extracellular catalytic domain of B4GALT1 (Globular catalytic domain, Leu126–Ser398) recombinantly expressed in HEK293 cells. It specifically transfers galactose from UDP-Galactose (UDP-Gal) onto N-acetylglucosamine (GlcNAc) to form non-reducing β1-4 linked galactose. This product can be applied to investigations into the mechanism of action of B4GALT1, inhibitor screening, and in vitro modification of glycoproteins. The protein carries an N-terminal His-tag, which can be removed via adsorption using corresponding anti-His antibody agarose resins, magnetic beads or nickel affinity columns.
