Daou N, Viader A, Cokol M, Nitzel A, Chakravarthy M, Afeyan R, et al.
Sci Rep . 2021 Jun; 11(1):11861. PMID: 34088912
Nonalcoholic steatohepatitis (NASH) is a complex metabolic disease of heterogeneous and multifactorial pathogenesis that may benefit from coordinated multitargeted interventions. Endogenous metabolic modulators (EMMs) encompass a broad set of molecular...

iScience . 2020 Oct; 23(10):101628. PMID: 33103071
Multifactorial disease pathophysiology is complex and incompletely addressed by existing targeted pharmacotherapies. Amino acids (AAs) and related metabolites and precursors are a class of endogenous metabolic modulators (EMMs) that have...

Hamill M, Jost M, Wong C, Bene N, Drennan C, Elliott S
Int J Mol Sci . 2013 Feb; 13(12):16899-915. PMID: 23443126
When exposed to known DNA-damaging alkylating agents, Escherichia coli cells increase production of four DNA repair enzymes: Ada, AlkA, AlkB, and AidB. The role of three enzymes (Ada, AlkA, and...

Goldman P, Ryan K, Hamill M, Howard-Jones A, Walsh C, Elliott S, et al.
Chem Biol . 2012 Jul; 19(7):855-65. PMID: 22840773
The indolocarbazole biosynthetic enzymes StaC, InkE, RebC, and AtmC mediate the degree of oxidation of chromopyrrolic acid on route to the natural products staurosporine, K252a, rebeccamycin, and AT2433-A1, respectively. Here,...

Hamill M, Jost M, Wong C, Elliott S, Drennan C
Biochemistry . 2011 Oct; 50(46):10159-69. PMID: 22004173
The process known as "adaptive response" allows Escherichia coli to respond to small doses of DNA-methylating agents by upregulating the expression of four proteins. While the role of three of...

Hamill M, Chobot S, Hernandez H, Drennan C, Elliott S
Biochemistry . 2008 Aug; 47(37):9738-46. PMID: 18717594
Thioredoxin reductases (TrxRs) are flavin-containing dithioloxidoreductases that couple reduction equivalents from the soluble NAD(P)H pool to the soluble protein thioredoxin (Trx). Previous crystallographic studies of the Escherichia coli enzyme (...

Biochemistry . 2008 Aug; 47(37):9728-37. PMID: 18717593
Thioredoxin reductases (TrxRs) regulate the intracellular redox environment by using NADPH to provide reducing equivalents for thioredoxins (Trxs). Here we present the cloning and biochemical characterization of a putative TrxR...

Ryan K, Howard-Jones A, Hamill M, Elliott S, Walsh C, Drennan C
Proc Natl Acad Sci U S A . 2007 Sep; 104(39):15311-6. PMID: 17873060
The biosynthesis of rebeccamycin, an antitumor compound, involves the remarkable eight-electron oxidation of chlorinated chromopyrrolic acid. Although one rebeccamycin biosynthetic enzyme is capable of generating low levels of the eight-electron...
