We examine the diversity of (M+)-activated enzymes by first comparing coordination in small molecules followed by a discussion of theoretical and practical aspects. Select examples of enzymes that utilize M+ as a cofactor (type I) or allosteric effector (type II) illustrate the structural basis ...
Pf MDH could not use NADP/NADPH as a cofactor, but used acetylpyridine adenine dinucleoide, an analogue of NAD. The enzyme exhibited strict substrate and cofactor specificity. The highest levels of Pf MDH transcripts were detected in trophozoites while the Pf MDH protein level remained high in...

Another key ion regulated by lysosomes is Fe2+which enters the cell via the endolysosomal system [32,33]. Tight regulation of cellular Fe2+is crucial as it is an important cofactor for enzymes in the electron transport chain [34]; however, high levels may promote the formation of toxic react...
Activated factor V is a cofactor protein that accelerates the production of thrombin by prothrombinase, an enzyme complex composed of factor Va, factor Xa, prothrombin, calcium ions, and a negatively charged phospholipid membrane. The activity of prothrombinase is regulated to ensure that adequate, ...
Because the Km of enkephalins with the latter enzyme was lower than with ACE, the second peptidyl dipeptidase was named the true "enkephalinase". Both enzymes are membranebound and contain zinc as a cofactor, but human NEP is not a second peptidyl dipeptidase. It differs from ACE in its ...
Activation of phenylalanine hydroxylase induces positive cooperativity toward the natural cofactor. Protein misfolding with loss-of-function of the enzyme phenylalanine hydroxylase (PAH) is the molecular basis of phenylketonuria in many individuals carryi...

Copper is an essential cofactor of enzymes in animals that may eventually lead to cell death even at moderate intracellular concentrations [30]. The liver is an important organ for copper metabolism in the body. It has been established that liver cirrhosis which increases susceptibility to HCC, sh...
binding domains" flavoproteins (tDBDF) superfamily using structural comparisons and other bioinformatics approaches shows how structural requirements associated with cofactor reactivity constrain the mode of protein–protein interactions while providing the major route for evolution of functional diversification. ...
