Title: Hiromi Katae: Innovator in Alkaline Protease Development

Introduction

Hiromi Katae is a notable inventor based in Kawachinagano, Japan. He has made significant contributions to the field of biochemistry, particularly in the development of novel alkaline proteases. His work has implications for various applications, including dental health.

Latest Patents

Katae holds a patent for a novel alkaline protease M.sub.3, which is distinguished from known alkaline proteases by its unique physiochemical properties. This protease operates optimally at a strong alkaline pH range of 9-12.5 and is not inhibited by common inhibitors such as FeSO.sub.4, diisopropyl fluorophosphate, ethylenediamine tetraacetate, and iodoacetic acid. Additionally, it exhibits glucosyltransferase inhibitory activity and has the lowest molecular weight among its counterparts. The alkaline protease M.sub.3 can be produced by cultivating a microorganism of the genus Streptomyces, specifically the Streptomyces globisporus B-1829 strain (ATCC 21553). This innovative enzyme is particularly useful for the prevention of dental caries.
