AI-driven structural analysis in biotechnology: a GS3 Science & Technology and Synthetic Biology case study.
Why in news
Researchers at the Innovative Genomics Institute (IGI) discovered the VIPR viral system using AI-assisted structural analysis to screen 2.3 million proteins.
Background
The VIPR system was identified by researchers Peter Yoon and Kenneth Loi using AI to screen 2.3 million protein structures. The system utilizes a 'gapped' coding strategy to form a triplex that silences genes and may explain the origins of Class 1 CRISPR.
Facts for Prelims
