Enzyme substrate positioning dynamics: To be electrostatic or not to be?
Feb. 9, 2024—Bioengineered enzymes are used in a wide variety of applications including chemical synthesis, waste degradation, fuel production, disease diagnosis and treatment. The development of efficient enzymes can be accelerated by understanding the catalytic origin of enzymes, a fundamental question in the field of chemistry. Catalysis is believed to rely largely on protein dynamics, one facet...

Delving into polymerase 伪-primase dynamics
Jan. 5, 2024—In eukaryotes, DNA replication relies on the synthesis of a chimeric RNA/DNA primer by the heterotetrameric polymerase 伪-primase (pol-prim) enzyme. The primers generated by pol-prim consist of 7-10 ribonucleotides followed by ~20 deoxyribonucleotides and are generated by distinct active sites in the primase and polymerase subunits. Both primase and polymerase 伪 consist of a catalytic...
A new toxin toolkit for C. diff
Dec. 1, 2023—Clostridioides difficile (C. diff) is a leading cause of diarrhea and healthcare-associated infections in the United States and recognized as an urgent threat by the Centers for Disease Control. Virulence of C. diff infections is believed to rely primarily on the production of two toxins: TcdA and TcdB. TcdA and TcdB are large homologous proteins...

Is DZA the new DNA? Structural and functional studies of a novel artificial pairing system
Nov. 3, 2023—Xeno nucleic acids (XNAs) are artificial pairing systems that replace the traditional deoxyribonucleic acid (DNA) system present in most organisms. XNAs are of particular interest in the discovery and development of therapeutics as synthetic molecules offer a wider range of metabolic stability, uptake, distribution and binding partners compared to native oligonucleotides. One of the most...

A glimpse into higher-order mRNP assemblies
Sep. 29, 2023—In eukaryotic cells, mRNA is transcribed in the nucleus. Protein factors rapidly bind to newly transcribed mRNA to form a messenger ribonucleoprotein (mRNP), which is exported to the cytoplasm for translation. One complex in humans vital for the formation and export of mRNPs is the transcription-export complex (TREX). TREX consists of the THO complex, an...
