Research Summary

The Jinich laboratory is a mixed computational and experimental group. The overarching goal of the Jinich lab is to develop computational methods that predict enzyme substrate chemical structure based on amino acid sequence, thereby unveiling previously unknown enzyme functions and expanding the repertoire of characterized enzymes. We employ machine learning techniques to generate powerful protein representations, and use systems biochemistry and functional genetics to experimentally validate our substrate predictions. Additionally, we plan to establish high-throughput enzyme activity assays to generate data that will further improve our machine learning models. Accelerating the prediction of so-called "orphan" enzyme substrates will be of value across diverse fields, from enabling advances in metabolic engineering and environmental microbiology to transforming our understanding and treatment of infectious diseases.

Key Contributions
  • Development of a mixed quantum chemical and machine learning approach to predict redox potentials of small molecule metabolites from molecular structure with high accuracy.
  • Systematic analysis of redox reaction networks relevant to prebiotic chemistry from a thermodynamic lens.
  • Built the Mycobacterium tuberculosis transposon sequencing database (MtbTnDb), compiling TnSeq screens from the literature and other datasets that quantitatively describe what mycobacterial genes are essential in which conditions for over 150 experiments.
  • Development of a statistical method to identify fitness profile correlations from functional genetics data as enabled by transposon sequencing (TnSeq) screens.
  • Identification and experimental validation of an enzyme module in M. tuberculosis of seven co-essential genes which form an enzyme module that helps Mtb counter the toxic effects of itaconate, an important antibacterial compound produced by the host during infection.
