We are just beginning to understand the metabolism of heavy metals and to use their
metabolic functions in biotechnology, although heavy metals comprise the major part of the …

Nickel even though recognized as a trace element, its metabolism is very decisive for certain
enzyme activities, maintaining proper cellular redox state and various other biochemical …

Sequences and available structures were compared for all the widely distributed
representatives of the P-loop GTPases and GTPase-related proteins with the aim of …

Hydrogenases (H2ases) catalyze the reversible oxidation of molecular hydrogen and play a
central role in microbial energy metabolism. Most of these enzymes are found in Archaea …

Nickel is an essential nutrient for plants. However, the amount of Ni required for normal
growth of plants is very low. Hence, with the level of Ni pollution in the environment …

Global modernization is responsible for industrialization, urbanization and several other
anthropogenic activities, which involves the huge application of heavy metals. Heavy metals …

Nickel is an essential nutrient for selected microorganisms where it participates in a variety
of cellular processes. Many microbes are capable of sensing cellular nickel ion …

Globally, rapidly increasing industrialization and urbanization have resulted in the
accumulation of higher concentrations of heavy metals in soils. The highly contaminated soil …

Enzymes possessing the capacity to oxidize molecular hydrogen have developed
convergently three class of enzymes leading to:[FeFe]-,[NiFe]-, and [FeS]-cluster-free …

Hydrogenases (H 2 ases) are metalloproteins. The great majority of them contain iron-sulfur
clusters and two metal atoms at their active center, either a Ni and an Fe atom, the [NiFe]-H 2 …
