Advanced Biology, Volume 5, Issue 4, April 2021., 2021 Graphene quantum dots (GQDs) induce antioxidative damage, alteration of phytohormone levels and mineral homeostasis, which eventually cause impaired photosynthesis and plant growth. Surface functionalization determines the reactive oxygen species generation and antioxidants oxidation capacity, which leads to different phytotoxicity of GQDs.

Generation of Oxidoreductases with Dual Alcohol Dehydrogenase and Amine Dehydrogenase Activity
Chemistry – A European Journal, Volume 27, Issue 10, Page 3315-3325, February 15, 2021., 2021 Lend me your hydrogen: Starting from an ϵ‐deaminating l‐lysine dehydrogenase, we created new variants that perform the reduction of aldehydes to alcohols and the reductive amination of aldehydes and ketones to amines. The reductive amination of ketones proceeded with excellent stereoselectivity.
