What is Biochemical and Molecular Research?
Biochemical and Molecular Research is the study of nucleotide biosynthesis pathways, including purine and pyrimidine metabolism, the structure and function of key enzymes such as CTP synthase, IMP dehydrogenase, and dihydroorotate dehydrogenase, and associated disorders like Lesch-Nyhan syndrome.
This field encompasses 61,039 published works on the regulation and metabolic pathways of nucleotide biosynthesis. It examines enzyme inhibition, including transition state analogue inhibitors, and genetic disorders stemming from nucleotide metabolism defects. Growth rate over the past five years is not available in the data.
Topic Hierarchy
Research Sub-Topics
Purine Biosynthesis
Research elucidates the de novo and salvage pathways leading to IMP, AMP, and GMP, including enzyme kinetics and allosteric regulation. Studies explore feedback inhibition and pathway flux in cancer and immune cells.
Pyrimidine Biosynthesis
This sub-topic investigates UMP synthesis via CAD supercomplex, CTP synthase glutamine amidotransferases, and dihydroorotase catalysis. Researchers study coordination of multifunctional enzymes and metabolic channeling.
IMP Dehydrogenase Inhibition
Studies design transition state analogs and allosteric inhibitors targeting IMPDH for immunosuppression and antiviral activity. Structure-function analyses reveal isoform selectivity and resistance mutations.
CTP Synthase Regulation
Researchers examine filamentation, GTP activation, and glutamine hydrolysis in CTP synthetase across species. Filament dynamics link enzyme activity to cellular nucleotide demands.
Lesch-Nyhan Syndrome
This area explores HPRT1 mutations causing purine overproduction, hyperuricemia, and neurobehavioral deficits. Research identifies neurotransmitter imbalances, gene therapy approaches, and animal models.
Why It Matters
Biochemical and Molecular Research enables advancements in structural biology, gene expression analysis, and disease mechanisms through techniques like protein purification and macromolecular structure determination. Nelson (1944) introduced a photometric adaptation of the Somogyi method for glucose determination, which improved reliability in measuring glucose in biological materials using modified copper reagents. Gorman et al. (1982) developed recombinant genomes expressing chloramphenicol acetyltransferase in mammalian cells, facilitating gene expression studies with pSV2-cat plasmids combining pBR322 elements and simian virus components. Liebschner et al. (2019) advanced Phenix software for X-ray, neutron, and electron diffraction, streamlining three-dimensional structure solutions essential for understanding biological processes and therapeutics development. These contributions support drug discovery, such as click chemistry applications noted by Kolb and Sharpless (2003), and tumor suppressor gene identification like the von Hippel-Lindau gene by Latif et al. (1993), impacting cancer research.
Reading Guide
Where to Start
'A PHOTOMETRIC ADAPTATION OF THE SOMOGYI METHOD FOR THE DETERMINATION OF GLUCOSE' by Nelson (1944) provides an accessible entry into biochemical assay development, demonstrating practical adaptations for reliable glucose measurement in biological materials.
Key Papers Explained
Nelson (1944) established foundational photometric assays for metabolites, building toward advanced expression systems in Gorman et al. (1982), who created pSV2-cat for mammalian protein production. Jacob and Monod (1961) provided genetic regulation frameworks that underpin enzyme studies, extended by Smith and Johnson (1988) in glutathione S-transferase fusion purification techniques. Liebschner et al. (2019) integrated these with Phenix for structure determination, connecting to Terwilliger and Berendzen (1999) automated MAD/MIR solutions.

Frequently Asked Questions
What are the main enzymes studied in nucleotide biosynthesis?
Key enzymes include CTP synthase, IMP dehydrogenase, and dihydroorotate dehydrogenase. These enzymes regulate purine and pyrimidine biosynthesis pathways. Inhibition studies focus on transition state analogue inhibitors.
What is Lesch-Nyhan syndrome?
Lesch-Nyhan syndrome is a disorder related to nucleotide metabolism. It arises from defects in purine biosynthesis pathways. The condition is highlighted in research on metabolic enzyme functions.
How does the photometric adaptation of the Somogyi method work for glucose determination?
Nelson (1944) adapted Somogyi-Shaffer-Hartmann copper reagents for colorimetric glucose measurement by omitting iodide and iodate, which interfere with the process. This modification ensures reliability in biological samples. The method established photometric quantification of glucose.
What is the role of pSV2-cat in molecular biology?
Gorman et al. (1982) constructed pSV2-cat as a recombinant genome directing chloramphenicol acetyltransferase expression in mammalian cells. It couples the beta-lactamase gene and origin from pBR322 to simian virus elements. This prototype enables gene expression studies.
How has Phenix software impacted structure determination?
Liebschner et al. (2019) describe Phenix developments for X-ray, neutron, electron diffraction, and cryo-microscopy. It simplifies workflows for three-dimensional macromolecular structures. These structures aid in biological process understanding and therapeutic development.
What did Jacob and Monod contribute to genetic regulation?
Jacob and Monod (1961) outlined genetic regulatory mechanisms in protein synthesis. Their work in 'Genetic regulatory mechanisms in the synthesis of proteins' established foundational models. It influences studies on enzyme and metabolic regulation.
