A fluorescent derivative of 6-mercaptoguanosine, S-(N-dansylaminoethyl)-6-mercaptoguanosine, was synthesized, and found to be a strong inhibitor of the uridine transport system of erythrocyte (Ki approximately 0.3 microM). The emission spectrum of th

The degradation kinetics of 5 × 10−5 M cyanocobalamin (B12) and hydroxocobalamin (B12b) in the presence of ascorbic acid (AH2) was studied in the pH range of 1.0–8.0. B12 is degraded to B12b which undergoes oxidation to corrin ring cleavage prod

Bacteriorhodopsin (bR) is characterized by a retinal-protein protonated Schiff base covalent bond, which is stable for light absorption. We have revealed a light-induced protonated Schiff base hydrolysis reaction in a 13-cis locked bR pigment (bR5.13

The l-mandelate dehydrogenase (L-MDH) from the yeast Rhodotorula graminis is a mitochondrial flavocytochrome b2 which catalyses the oxidation of mandelate to phenylglyoxylate coupled with the reduction of cytochrome c. We have used the N-terminal seq

Inward barium current (IBa) through voltage-gated calcium channels was recorded from chick cochlear hair cells using the whole-cell clamp technique. IBa was sensitive to dihydropyridines and insensitive to the peptide toxins omega-agatoxin IVa, omega

Three surfactants (chlorpromazine hydrochloride, thioridazine hydrochloride, and sodium deoxycholate) are found to absorb just as strongly into the protein-containing membranes of erythrocytes as into the phospholipid bilayers of synthetic vesicles.

Two Tn5 lac insertions into the Myxococcus genome at sites omega 4414 and omega 4473, which are separated by 550 nucleotides, inactivate fruiting body development. Sporulation is decreased 100- to 10,000-fold. At least two genes, devR and devS, are t

The behavioral response of Escherichia coli to electric shock in 10(-2) M potassium phosphate plus 10(-4) M potassium EDTA was studied. When presented with a 150-V/cm electric shock that lasted 250 ms, the bacteria at first exclusively ran, then excl

Urease of Helicobacter pylori (formerly Campylobacter pylori) is believed to represent a critical virulence determinant for this species. Ammonia generated by hydrolysis of urea may protect the acid-sensitive bacterium as it colonizes human gastric m
Transient absorption spectroscopy in the time range from -1 ps to 4 ns, and over the wavelength range from 420 to 550 nm, was applied to the Glu46Gln mutant of the photoactive yellow protein (PYP) from Ectothiorhodospira halophila. This has allowed u
