   Sammanfattning : Nickel enzymes have been suggested, through numerous phylogenetic studies, to have been among the very first catalytic compounds on the early Earth, possibly present in the last universal common ancestor (LUCA) or prior to the onset of life. This is because of the type of reactions catalyzed by some of these enzymes, the nature of organisms that utilize them, their distribution in the tree of life, and their key roles in what is now thought of as possibly one of the oldest carbon fixation pathways, the Wood-Ljungdahl (WL) pathway.
