Anthrax lethal toxin is a binary bacterial toxin consisting of two proteins, protective antigen (PA) and lethal factor (LF), that self-assemble on receptor-bearing eukaryotic cells to form toxic, non-covalent complexes. PA(63), a proteolytically acti

Ribose-modified highly-fluorescent sulfoindocyanine ATP and ADP analogs, 2′(3′)- O -Cy3-EDA-AT(D)P, with kinetics similar to AT(D)P, enable myosin and actomyosin ATPase enzymology with single substrate molecules. Stopped-flow studies recording bo

Activation of the proenzyme form of the malarial protease PfSUB-1 involves the autocatalytic cleavage of an Asp-Asn bond within the internal sequence motif (215)LVSADNIDIS(224). A synthetic decapeptide based on this sequence but with the N- and C-ter

Eleven individual hyperimmune rabbit polyclonal anti-fluorescein Fab fragment preparations were resolved into heterogeneous subfractions based on differential dissociation times from a specific adsorbent. Four Fab subfractions (i.e., 0.1-, 1.0-, 10-,

Although most biochemistry curricula include some treatment of light absorption and spectrophotometry, discussion of fluorescence spectroscopy is generally omitted. This omission is unfortunate given the increasing use of fluorescence in many fields

Fab fragments derived from ten different IgG populations of hyperimmune rabbit polyclonal anti-fluorescein antibodies were further resolved into subfractions based on differences in time-dependent dissociation from an FITC-adsorbent in the presence o

In this report the temperature dependence of photoinduced electron transfer between both singlet- and triplet-state uroporphyrin (1URO and 3URO, respectively) and the heme group of ferricytochrome c (Cc) has been examined. Analysis of the forward ele

Fluorescence polarization was first observed in 1920 and during the next few decades the theoretical foundations of the phenomenon were clearly established. In the last two decades of the 20(th) century, fluorescence polarization became one of the mo
