Title: Innovations of Daniel H Lajiness

Introduction

Daniel H Lajiness is a notable inventor based in Fairfield, OH (US). He has made significant contributions to the field of biochemistry, particularly in the development of engineered enzymes. With a total of six patents to his name, Lajiness has demonstrated a commitment to advancing scientific knowledge and practical applications.

Latest Patents

Lajiness's latest patents focus on engineered aryl sulfate-dependent enzymes. These inventions provide several non-naturally occurring sulfotransferase enzymes that have been engineered to react with aryl sulfate compounds as sulfo group donors. Instead of the natural substrate 3'-phosphoadenosine 5'-phosphosulfate (PAPS), these enzymes interact with heparosan-based polysaccharides, particularly heparan sulfate, as sulfo group acceptors. Each engineered sulfotransferase enzyme exhibits biological activity characterized by the position within the heparosan-based polysaccharide that receives the sulfo group. This includes activities such as glucosaminyl N-sulfotransferase, hexuronyl 2-O sulfotransferase, glucosaminyl 6-O sulfotransferase, and glucosaminyl 3-O sulfotransferase. Additionally, methods for using these engineered sulfotransferases to produce sulfated heparosan-based polysaccharides, including those with anticoagulant activity, are also provided.
