Human Carbonic Anhydrases
Sequence studies of human erythrocyte carbonic anhydrase B show that it contains 256 residues. A series of relatively small peptides soluble in aqueous solutions obtained by chymotryptic and tryptic digestion of the enzyme, large peptides containing only COOH-terminal lysine or arginine as well as those resulting from more limited cleavage of the enzyme, and cyanogen bromide cleavage products s...
متن کاملPolyamines and α-Carbonic Anhydrases.
Natural products represent a straightforward source for molecular structures bearing a vast array of chemical features and potentially useful for biomedical purposes. Recent examples of this type include the discovery of the coumarins and the polyamine natural products as atypical chemotypes for the inhibition of the metalloenzymes carbonic anhydrases (CAs; EC 4.2.2.1). CA enzymes are establish...
متن کاملCarbonic Anhydrases: Role in pH Control and Cancer
The pH of the tumor microenvironment drives the metastatic phenotype and chemotherapeutic resistance of tumors. Understanding the mechanisms underlying this pH-dependent phenomenon will lead to improved drug delivery and allow the identification of new therapeutic targets. This includes an understanding of the role pH plays in primary tumor cells, and the regulatory factors that permit cancer c...
متن کاملTransport metabolons with carbonic anhydrases
THE CONCEPT OF THE TRANSPORT METABOLON A metabolon has been defined as a “temporary, structural-functional, supramolecular complex of sequential metabolic enzymes and cellular structural elements, in which metabolites are passed from one active site to another without complete equilibration with the bulk cellular fluids” (Srere, 1985, 1987). This substrate channeling should decrease transit tim...
متن کاملStructure and expression of mammalian carbonic anhydrases.
tions make it possible to ascribe specific roles to particular residues, such as the conserved glycine residues 141 at bends in the basic fold which appear to constitute alcohol dchydrogenase per se. Each of these concepts can now be further tested by directed mutagenesis. Regarding the enzymic mechanisms, the basic properties of the zinc dehydrogenases have essentially been known for some time...
