Anwendung

A heterobifunctional cross-linking reagent containing a sulfhydryl-specific group and a photo-active group. Typically, coupled initially by thioether to molecule containing free sulfhydryl buffered at pH 6.8 (6.5-7.0). Second bonding occurs during UV irradiation (250 nm) via diradical excited state. Benzophenones demonstrate greater specificity for C-H insertion and are more stable in water than analogous reagents. In general they are more efficient in attachment because they may be repeatedly irradiated; however, a more intense irradiation may be required. The benzophenone is not sensitive to reduction compared to analogous reagents.

Bacterial detoxification of mercuric ion depends on the presence of one or more integral membrane proteins (MerT and/or MerC) whose postulated function is in transport of Hg2+ from a periplasmic Hg2+-binding protein (MerP) to cytoplasmic mercuric reductase. In this study

LEC-1 is the first tandem repeat-type galectin isolated from an animal system; this galectin has two carbohydrate recognition domains in a single polypeptide chain. Because its two lectin domains have different sugar-binding profiles, these domains are thought to interact with

The interaction sites of rabbit skeletal troponin I (TnI) with troponin C (TnC), troponin T (TnT), tropomyosin (Tm) and actin were mapped systematically using nine single cysteine residue TnI mutants with mutation sites at positions 6, 48, 64, 89, 104

Treatment of murine leukaemia virus reverse transcriptase with benzophenone 4-maleimide inactivates DNA polymerase activity, but has no effect on the RNAase H function. Kinetic measurements indicated that benzophenone 4-maleimide is a competitive inhibitor with respect to template-primer binding, but is

Using a combination of cysteine mutagenesis and covalent cross-linking, we have identified subunits in close proximity to specific sites within subunit B of the vacuolar (H(+))-ATPase (V-ATPase) of yeast. Unique cysteine residues were introduced into subunit B by site-directed mutagenesis
