Introduction. Molybdenum (Mo) is a transition element present in relatively small amounts in the environment, with 2.4 mg kg−1 in the lithosphere and 0.2–36 mg kg−1 in soils (Broadley et al., 2012).Despite its low abundance in the environment, it is an essential micronutrient for almost all living organisms except for certain strains of …
Details
Function in Plants The transition element molybdenum is essential for most organisms and occurs in more than 60 enzymes catalyzing diverse oxidation–reduction reactions .Although the element is capable of existing in oxidation states from 0 to VI, only the higher oxidation states of IV, V, and VI are important in biological systems.
Details
The transition element molybdenum (Mo) occurs in a wide range of metalloenzymes in bacteria, fungi, algae, plants and animals where it forms part of the active centers of these enzymes (for reviews see Schwarz and Mendel 2006; Bittner and Mendel 2010).In order to gain biological activity, Mo has to be complexed by a pterin …
