The min-max algorithm is then applied to normalize the dataset to a specific scale, preventing the prediction model from …

An Examination Of Lysine Acetylation In The Context Of Bacterial Metabolism, Translation, And Regulation Of Gene Expression, Thomas Patrick Bank

Dissertations

Post-translational modifications are a critical tool bacteria employ to survive the challenges of microbial life. Acetylation continues to gain more recognition as a modification of unique importance because the sources of acetylation – acetyl-phosphate and acetyl-coenzyme-A – are critical metabolites associated with central carbon metabolism, acetate overflow metabolism and acetate assimilation. This suggests that acetylation, indelibly coupled to metabolic flux, integrates metabolic sensing with any cellular process or pathway where an acetylation alters the function of a protein. Intuitively, this makes sense. Of course, a bacterial cell would coordinate any cellular process closely with the amount of energy available to …
