Improved laccase production by Trametes versicolor using Copper-Glycyl-L-Histidyl-L-Lysine as a novel and high-efficient inducer.
Editor's note
This is an industrial biotechnology study, not a health study. Researchers used copper-GHK (GHK-Cu) as an additive to boost production of laccase, an enzyme, by the fungus Trametes versicolor in fermentation, reporting a roughly 12.8-fold increase in laccase activity versus no additive and better performance than plain copper sulphate at the same copper level. The proposed reason is that GHK-Cu made the fungal cell membrane more permeable with less damage, improving copper uptake and switching on laccase genes. For AllAboutAminos readers the relevance to human use is essentially nil: the work concerns a fungal bioprocess for producing enzymes for industry, with no bearing on GHK-Cu's cosmetic, wound-healing or systemic applications in people. It is included here only because it involves the same molecule. The one transferable observation, that GHK-Cu can act as an efficient, comparatively gentle copper carrier into cells, is a chemistry point, not evidence of any benefit or safety in humans.
Plain-language abstract
This study is about manufacturing an enzyme, not about human health. Scientists were trying to get a fungus (Trametes versicolor) to produce more of an enzyme called laccase, which is useful in industry. They added the copper peptide GHK-Cu to the growth medium and found that laccase production jumped about 12.8 times higher than without it, and was better than adding plain copper sulphate at the same copper amount. In a larger 5-litre tank, the method still worked well. The researchers explain that GHK-Cu helped by making the fungal cells' outer membrane more permeable without harming them much, so the cells took up and used copper more easily and switched on the genes that make laccase. They suggest GHK-Cu could be a gentle, non-toxic way to carry copper into cells to boost enzyme production. This is an industrial fermentation result about fungi; it says nothing about using GHK-Cu in or on the human body.
