Robots and Minimal, Physics-Informed Features: A Hybrid Framework for Enzyme Catalysis. [PDF]

Adv Sci (Weinh)
Robotic experimentation and physics‐informed machine learning combine to predict enzyme substrate scope. With a handful of interpretable features derived from docking and quantum mechanics calculations, our model rivals descriptor‐heavy AI approaches and extrapolates to unseen substrates and enzyme classes.

Esterase-Activated Perthiocarbonate Persulfide Donors Provide Insights into Persulfide Persistence and Stability

, 2022
Persulfides (RSSH) are important reactive sulfur species (RSS) that are intertwined with the biological functions of hydrogen sulfide (H2S). The direct study of persulfides is difficult, however, due to their both nucleophilic and electrophilic character,

Production of an esterase from Fusarium oxysporum catalysing transesterification reactions in organic solvents

, 1998
The production of an esterase by Fusarium oxysporum, grown on tomato skins as the sole carbon source, was studied in submerged and solid state cultures. Under optimum growth conditions, enzyme yields as high as 7·3 U/ml of culture medium and 19·4 U/g of ...
