Murburn concept and murzymes in 2023: celebrating 25th year of pursuit

Kelath Murali Manoj

Abstract

Murburn concept (from “mured burning”; signifies that redox processes involving diffusible reactive species form indispensable facets of governing key metabolic/physiological facets of life) dispels the traditional/aesthetic perception that diffusible reactive species (DRS) are merely wasteful/chaotic agents and enlightens that the processes mediated by DRS are necessary for carrying out crucial/routine cellular functions. Such DRS-sponsored stochastic activities evolutionarily pre-date the deterministic affinity-driven catalysis and signal transduction cascades of classical/acclaimed protein-functions. My pursuits in this regard started in 1999 with seemingly innocuous explorations and serendipitous observations while working on a fungal heme-peroxidase in Lowell Hager’s (elected member, National Academy of Sciences, USA) lab at University of Illinois (Urbana-Champaign). Since then, murburn concept has transformed into one of the founding pillars of cell/life sciences. Biomedical Reviews played a pivotal role by serving as the first portal publishing/disseminating my articles critiquing the acclaimed bioenergetic explanations from Peter Mitchell and Paul Boyer; namely- chemiosmosis/proton motive force and rotary ATP-synthesis (recognized with Nobel Prizes in 1978 and 1997, respectively). These papers also advocated murburn concept as a viable alternative for explaining cellular powering by mitochondria, i.e. oxidative phosphorylation and thermogenesis. Herein, adopting a balanced measure of gratitude and grievances, I document the salient developments of the last few years’ progression on murburn concept and present my subjective impressions on its impact/prospects in the future.
