Umea University For the first time, researchers at Umeå University have succeeded in showing how the DNA polymerase epsilon enzyme builds new genomes. The detailed image produced by these researchers shows how mutations that can contribute to the development of colorectal cancer and cervical cancer lead to changes in the structure of the protein. This study will be published in the journal Nature Structural and Molecular Biology. Genomes are built from pairs of long strands of DNA. In...

The novel Natural Sciences Bibliographic Web Portal aims to provide comprehensive bibliographic information on the basic and applied life, earth and health sciences and has published over 184,800 references and 133,600 tags. Scien.net has now newly included the category Polymerase which is an enzyme associated with polymers of nucleic acids such as the deoxyribonucleic acid (DNA) and ribonucleic acid (RNA), and on Reductase, which is an enzyme that is known for catalyzing reduction and...

Fluorescent Tags Help Scientists Solve Mystery Of Human DNA Replication

redOrbit Staff & Wire Reports - Your Universe Online Scientists at Penn State University have discovered how a vital step in the human DNA replication process — the loading of molecular structures known as sliding clamps onto DNA molecules — is performed. The researchers say their work, the results of which were published in Tuesday´s edition of the journal eLife, will help uncover some of the mystery surrounding this crucial part of the chemical replication...

St. Jude Children's Research Hospital study shows how compounds blocking an enzyme universal to all influenza viruses may allow development of new antiviral drugs that also avoid the problem of drug resistance Scientists at St. Jude Children's Research Hospital have reported details of how certain drugs can precisely target and inhibit an enzyme essential for the influenza virus' replication. Since all strains of the virus require the same functioning enzyme, researchers believe their...

The discovery made by Dr. François Robert's team confirms the universality of an essential cellular process Dr. François Robert, molecular biology researcher at the Institut de recherches cliniques de Montréal (IRCM), and his team confirmed that the phosphorylation of RNA polymerase II, a key enzyme in the process of gene expression, is uniform across all genes. This discovery, which contributes to numerous debates on the topic within the scientific...

New research published in BioMed Central's open access journal Cell & Bioscience is the first to show that left-handed Z-DNA, normally only found at sites where DNA is being copied, can also form on nucleosomes. The structure of DNA which provides the blueprint for life has famously been described as a double helix. To save space inside the nucleus, DNA is tightly wound around proteins to form nucleosomes which are then further wound and compacted into chromatin, which is further...

Scientists have deciphered the structure of an essential part of Mediator, a complex molecular machine that plays a vital role in regulating the transcription of DNA. The research adds an important link to discoveries that have enabled scientists to gain a deeper understanding of how cells translate genetic information into the proteins and processes of life. The findings, published in the July 3 advance online issue of the journal Nature, were reported by a research team led by Yuichiro...
