Identification of a Reaction Intermediate and Mechanism of Action of Intermediary Enzymes in Plumbagin Biosynthetic Pathway

Scaling up is a problem that a lot of biotechnologists find difficult, in terms of manufacturing techniques and products; that’s where we provide biocatalytic solutions at Kcat! The above schema is an intermediary reaction in the Plumbagin Biosynthetic Pathway. We at Kcat have identified two critical steps and respective enzymes in the synthesis of Plumbagin,...

Quantum Tunnelling!

Kcat Enzymatic we are working on the similar reactions of Cytochromes as in the Nobel Laureate Dr. Arnold’s lab, however by a different technology that uses Quantum Molecular Dynamics. We wonder if enzymatic reactions take the aid of quantum tunneling effects; specifically, could it be heavy atom tunneling! A quantum mechanical phenomenon where particles penetrate...

Identification of Cryptic Sites/Interactions using Probe-Based Induction Algorithm (MIST)®

Cryptic pockets are sites on enzymes that only become apparent when ligands (substrate, co-substrate, cofactor) binds. They do not correspond to local minima in the computed conformational free energy landscape of the un-liganded proteins. Hence, they close in all the molecular dynamics simulations performed. Their formation is also known to be an interplay between both...

Kcat’s Technology used to derive variants to achieve kg level Substrate conversion

Schematic representation of Kcat’s Technology used to derive variants to achieve kg level substrate conversion with desired regioselectivity, stereospecificity, and enantiomeric excess. A system of Micrometer size with higher enzyme and substrate concentrations at varying pH, temperature, cofactor, co-substrate, and solvent conditions is simulated for microseconds. Information Capturing Technologies:A 7th Dimensional Grid made of Quantum beads that captures...

The patented technology works on Quantum mechanics-based probes/grid points, and real solvation using semi-empirical QM simulations. The dynamic probes atoms in the grid are replaced based on the neighbor-neighbor contacts in the conformational transitions. The Dynamic grid points capture high-resolution details of the enzymatic reaction. The method was implemented on an R-specific transaminase enzyme and...
