Title: Yoon-Suk Oh: Innovator in Biochemical Engineering
Introduction
Yoon-Suk Oh is a prominent inventor based in Yongin-si, South Korea. He has made significant contributions to the field of biochemical engineering, particularly through his innovative patents. With a total of 5 patents, his work focuses on enhancing biochemical processes and developing novel microorganisms.
Latest Patents
One of Yoon-Suk Oh's latest patents is the ammonia-specific 5'-XMP aminase mutant. This invention discloses ammonia-specific 5'-XMP aminase mutants and a method for preparing them. A mutation is introduced into the active site of glutamine-dependent catalysis in 5'-XMP aminase. The resulting mutant is devoid of glutamine-dependent activity and specifically reacts with external ammonia to convert 5'-XMP into 5'-GMP. This ammonia-specific mutant is more stable within cells compared to the wild type and can be useful in the industrial conversion of 5'-XMP into 5'-GMP.
Another notable patent involves a microorganism that produces 5'-Xanthylic acid. This invention relates to a microorganism obtained by treating KCCM 10488, which produces 5'-Xanthylic acid as a parent strain, with UV radiation and mutation derivatives such as N-methyl-N'-nitro-N-nitrosoguanidine (NTG). This microorganism exhibits resistance to 5-fluorotryptophan, enhancing the biosynthesis of N5-N10-tetrahydrofolate, which is crucial for transferring two formyl groups during the process of purine biosynthesis. This innovation allows for the accumulation of 5'-Xanthylic acid in culture medium at a high yield and concentration rate during fermentation.
