RIBONUCLEOTIDE REDUCTASES [PDF]
Annual Review of Biochemistry, 1998 Ribonucleotide reductases provide the building blocks for DNA replication in all living cells. Three different classes of enzymes use protein free radicals to activate the substrate. Aerobic class I enzymes generate a tyrosyl radical with an iron-oxygen center and dioxygen, class II enzymes employ adenosylcobalamin, and the anaerobic class III enzymes

Chromium bioremediation by Alcaligenes sp. strain newly isolated from chromite mine of Sabzevar [PDF]
Journal of Advances in Environmental Health Research, 2017 In this work, CKCr-6A strain was found to be highly resistant to some toxic heavy metals such as Cr+6, Cr+3, Cu+2, Co+2, Cd+2, Pb+2, Hg+2, U+6, tellurium, and selenite. Herein, high chromate tolerance of an isolated strain is reported with a high minimum
