Title: Yijun Chen: Innovator in Nitric Oxide Synthase Research

Introduction

Yijun Chen is a prominent inventor based in Iowa City, IA (US). He has made significant contributions to the field of nitric oxide synthase research, holding a total of 3 patents. His work focuses on the synthesis and regulation of nitric oxide, a crucial molecule in various biological processes.

Latest Patents

One of Yijun Chen's latest patents is for a novel constitutive nitric oxide synthase (NOS) that utilizes both arginine and arginine-rich peptides, oligopeptides, or proteins, such as bradykinin (BK), as substrates in the synthesis of nitric oxide (NO). This invention also includes methods for controlling, regulating, or modulating NO synthesis in a subject. Another significant patent involves the purification of nitric oxide synthase from rat brain. This NOS protein is purified to a specific activity at least 6,360-fold that of a crude tissue preparation. The protein has a denatured molecular weight of 105 kD determined by SDS-PAGE and a dimeric molecular weight of 230 kD determined by gel filtration. It requires FAD, FMN, Ca²⁺, and tetrahydropterin for the production of nitric oxide from L-arginine or an arginine-rich peptide, oligopeptide, or protein substrate.
