Structural modeling studies of aldehyde dehydrogenase X: insights into key interactions in the tetrameric assembly of the isoenzyme.

Human mitochondrial aldehyde dehydrogenase is a member of superfamily of multisubunit enzymes, catalyzing the conversion of a broad range of aldehydes to corresponding acids via the NAD (P) (+)-dependent irreversible reaction. They play an important role in the detoxification of acetaldehyde, in the development of alcohol sensitivity and human alcohol-related disorders. The study aimed to understand the role of conserved residues by comparing similarities and differences between the two isoenzymes.

Electrolytic recovery of chromium salts from tannery wastewater.

Tannery wastewater collected from a local leather industry in Peshawar, Pakistan was subjected to DC electrolysis in a simple cell having two static sheet electrodes and stirring assembly after proper dilution and adjustment to desired conditions. One percent HNO(3) and 1% NaHCO(3) were used as electrolytes and pH adjusters. The latter salt also worked as sodium source for anodic deposition of Na(2)Cr(2)O(7).
