RNA-editing enzyme, molecular model
RNA-editing enzyme. Molecular model of a left-handed, RNA double helix (Z-RNA, centre) bound by the Z alpha domain of the human RNA-editing enzyme ADAR1 (double-stranded RNA adenosine deaminase, red and blue). ADAR1 de-stabilises double stranded RNA (ribonucleic acid) by converting adenosine to inosine in the genetic sequence. ADAR1 is needed for the breakdown of adenosine from food and for the turnover of nucleic acids (RNA and DNA) in tissues

EDITORS COMMENTS
This molecular model illustrates the interaction between Z-RNA, a left-handed RNA double helix (centre), and the Z alpha domain of the human RNA-editing enzyme ADAR1 (red and blue). ADAR1 is a double-stranded RNA adenosine deaminase that plays a crucial role in the de-stabilisation of double-stranded RNA (dsRNA). The enzyme converts adenosine to inosine in the genetic sequence, which is essential for the breakdown of adenosine from food and the turnover of nucleic acids (RNA and DNA) in various tissues. In this model, the Z alpha domain of ADAR1 is shown binding to the Z-RNA double helix. The white background highlights the intricate details of the molecular structures. The space-filling representation of the proteins and nucleic acids provides a clear visualization of the molecular interactions at the atomic level. ADAR1 is an essential enzyme for maintaining cellular homeostasis, as it helps to prevent the accumulation of dsRNA, which can trigger an unwanted immune response. The deamination process catalyzed by ADAR1 is critical for various biological processes, including alternative splicing, antiviral defense, and neurodevelopment. The cut-out visualization of the molecular model emphasizes the intricate nature of the interactions between the RNA double helix and the ADAR1 enzyme, offering a unique perspective on the molecular mechanisms underlying RNA editing. This illustration serves as a valuable resource for researchers and students in the fields of biology, biochemistry, genetics, proteomics, and molecular biology, providing insights into the structure and function of RNA-editing enzymes and their role in maintaining cellular health.
