Picosecond transient absorption spectra of rhodopsin and isorhodopsin were measured at room temperature with a double-beam laser spectrophotometer after excitation at 355 nm. Photolysis studies were performed on rhodopsin solubilized in two different detergents (digitonin and 3-[(3-cholamidopropyl)dimethylammonio]-1-propanesulfonate). The resulting rhodopsin/bathorhodopsin

Bovine brain adenylate cyclase was solubilized with 3-[(3-cholamidopropyl)dimethylammonio]-1-propanesulfonate (CHAPS), sodium cholate, sodium deoxycholate, or these detergents plus (NH4)2SO4. The specific activity of the extract obtained with 13 mM CHAPS alone was several times those of the other detergent extracts with

Receptors that reversibly bind opiates and opioid peptides have been solubilized from brain and neuroblastoma-glioma hybrid cell NG108-15 membranes. Active receptors are specifically solubilized with a new type of detergent 3-[(3-cholamidopropyl)dimethylammonio]-1-propanesulfonate, which is a zwitterionic derivative of cholic acid. The

The biguanide metformin is widely prescribed for Type II diabetes and has anti-neoplastic activity in laboratory models. Despite evidence that inhibition of mitochondrial respiratory complex I by metformin is the primary cause of its cell-lineage-specific actions and therapeutic effects, the molecular
