The Role Of Glycosylase In DNA Repair
Glycosylase enzymes play a crucial role in the repair process of damaged DNA. Specifically, they are responsible for detecting and removing abnormal bases that may have been incorrectly incorporated into the DNA strand, often due to exposure to factors like UV radiation, chemicals, or other environmental stressors.
When glycosylase identifies a damaged base, it cleaves the bond between the sugar and the base in the DNA molecule, effectively removing the faulty base. This initial step is essential in initiating the repair process within the cell.
Following the removal of the damaged base by glycosylase, the DNA polymerase enzyme comes into play. DNA polymerase fills in the gap left behind with the correct nucleotide sequence, based on the undamaged strand of DNA as a template. This ensures that the DNA strand is accurately restored to its original state.
Overall, the coordinated action of glycosylase and other repair enzymes in the DNA repair pathway is vital for maintaining genomic stability and integrity. Without these mechanisms, DNA damage could accumulate over time, potentially leading to mutations, genetic disorders, or even cell death.
Researchers continue to study glycosylase enzymes and their role in DNA repair processes, aiming to further understand how they function and how their activity can be leveraged for potential therapeutic interventions in conditions related to DNA damage and genomic instability.

Why DNA Repair Matters Also known as photodamage, the skin’s DNA is very susceptible to damage from UV light. Avoid the consequences of UV exposure. 80% of skin aging is due to the sun and no sunscreen is 100% effective. Your skin’s DNA is subject to daily environmental assaults accelerating skin aging. Your body can only process and repair about 50% of this damage in any given day. However, your skin is not defenseless against this damage. Where Photozyme Comes In Thanks to our DNA Enzyme Technology, our products utilize a targeted delivery of natural repair enzymes to help prevent the signs of skin aging from surfacing. These enzymes are:
Why Sunscreen Is Not Enough Below you will see a bar chart referencing why sunscreen is simply not enough. Researchers intended to study the exposure of human skin to ultraviolet radiation (UVR). UVR exposure results in the formation of DNA photolesions which eventually give rise to photoaging, mutations, cell death, and even carcinogenic events. However, when a DNA repair enzyme, such as photolyase, is introduced it works to reverse damage caused by that UVR exposure. The intention was to investigate if the addition of photolyase works to enhance the protection of sunscreen. After testing, they found that photolyase with the addition of sunscreen was superior to only using sunscreen alone. The major finding (shown below) gives weight to the thinking that photolyase is a helpful addition to your skincare routine. This may make a world of difference as we all work to prevent UVR-induced DNA damage.
