Redox cofactors insertion in prokaryotic molybdoenzymes occurs via a conserved folding mechanism

A major gap of knowledge in metalloproteins is the identity of the prefolded state of the protein before cofactor insertion. This holds for molybdoenzymes serving multiple purposes for life, especially in energy harvesting. This large group of prokaryotic enzymes allows for coordination of molybdenum or tungsten cofactors (Mo/W-bisPGD) and Fe/S clusters. Here we report the structural data on a ...

Ribozymes that use redox cofactors *

This review summarizes the history and most recent advances in aptamers and ribozymes that bind and use redox(reduction–oxidation) cofactors. Redox reactions, catalyzed by protein enzymes in an extant world, play a central role in the metabolism of numerous biological molecules in the living organisms. The burden of catalyzing these reactions in a preprotein-based world (i.e., the hypothesized ...

Bacterial molybdoenzymes: old enzymes for new purposes.

Molybdoenzymes are widespread in eukaryotic and prokaryotic organisms where they play crucial functions in detoxification reactions in the metabolism of humans and bacteria, in nitrate assimilation in plants and in anaerobic respiration in bacteria. To be fully active, these enzymes require complex molybdenum-containing cofactors, which are inserted into the apoenzymes after folding. For almost...

The universally conserved prokaryotic GTPases.

Members of the large superclass of P-loop GTPases share a core domain with a conserved three-dimensional structure. In eukaryotes, these proteins are implicated in various crucial cellular processes, including translation, membrane trafficking, cell cycle progression, and membrane signaling. As targets of mutation and toxins, GTPases are involved in the pathogenesis of cancer and infectious dis...
