Table 3.

Bacterial families with members containing urease, uricase, tryptophanase, and p-cresol producing enzymes which were more abundant in ESRD group and the bacterial families with members possessing phosphotransbutyrylase and butyrate kinase which were less abundant in ESRD patients compared to healthy control group.

Enzyme Name	Matched Families
Urease	Alteromonadaceae, Cellulomonadaceae, Clostridiaceae, Dermabacteraceae, Enterobacteriaceae, Halomonadaceae, Methylococcaceae Micrococcaceae, Moraxellaceae, Polyangiaceae, Pseudomonadacea, and Xanthomonadaceae
Uricase	Cellulomonadaceae, Dermabacteraceae, Micrococcaceae, Polyangiaceae, and Xanthomonadaceae
Tryptophanase	Clostridiaceae, Enterobacteriaceae, and Verrucomicrobiaceae
p-Cresol Production enzymes	Clostriadiaceae, and Enterobacteriaceae
*Phosphotransbutyrylase	Lacctobacillaceae, and Prevotellaceae
*Butyrate Kinase	Lacctobacillaceae, and Prevotellaceae

^*Asterisk indicates the assessment of enzymatic function only in bacterial families of lower abundance in ESRD individuals.
