Disease

[CAH2_HUMAN] Defects in CA2 are the cause of osteopetrosis autosomal recessive type 3 (OPTB3) [MIM:259730]; also known as osteopetrosis with renal tubular acidosis, carbonic anhydrase II deficiency syndrome, Guibaud-Vainsel syndrome or marble brain disease. Osteopetrosis is a rare genetic disease characterized by abnormally dense bone, due to defective resorption of immature bone. The disorder occurs in two forms: a severe autosomal recessive form occurring in utero, infancy, or childhood, and a benign autosomal dominant form occurring in adolescence or adulthood. Autosomal recessive osteopetrosis is usually associated with normal or elevated amount of non-functional osteoclasts. OPTB3 is associated with renal tubular acidosis, cerebral calcification (marble brain disease) and in some cases with mental retardation.[1] [2] [3] [4] [5]

Function

[CAH2_HUMAN] Essential for bone resorption and osteoclast differentiation (By similarity). Reversible hydration of carbon dioxide. Can hydrate cyanamide to urea. Involved in the regulation of fluid secretion into the anterior chamber of the eye.[6] [7]

Publication Abstract from PubMed

Intermolecular interactions of eleven different fluoroaromatic inhibitors are probed within the scaffolding of the crystal lattice of Phe-131-->Val carbonic anhydrase II. The degree and pattern of fluorine substitution on the inhibitor benzyl ring modulate its size, shape, and electronic character. In turn, these properties affect the geometry of intermolecular interactions between the fluoroaromatic rings of two different inhibitor molecules bound in the crystal lattice, as determined by X-ray crystallography. Depending on the degree and pattern of fluorine substitution, we observe a face-to-face (aromatic-aromatic) interaction, an atom-to-face (carbonyl-aromatic) interaction, or no interaction at all. These interaction geometries are analyzed with regard to van der Waals, electrostatic, and possible charge-transfer effects. For the aromatic-aromatic interactions investigated in this study, with aromatic ring quadrupoles specifically "tuned" by the degree and pattern of fluorination, the structural results suggest that London forces and charge-transfer complexation dominate over weakly polar electrostatic interactions in the association of aromatic ring pairs.
