The dynein motor domain consists of a ring of six AAA domains with a protruding microtubule-binding stalk and a C-terminal domain of unknown function. To understand how conformational information is communicated within this complex structure, we produced a series of

Endoplasmic reticulum (ER)-enriched vesicles from etiolated hypocotyls of mung bean seedlings (Vigna radiata) were successfully isolated using Ficoll gradient and two-phase (polyethylene glycol-dextran) partition. The ER-enriched vesicles contained inorganic pyrophosphate (PPi) hydrolysis and its associated proton translocating activities. Antiserum prepared

The structure of sodium imidodiphosphate has been determined by single crystal x-ray diffraction. The P-N-P bond angle (127.2 degrees) and P-N bond distance (1.68 angstroms) are remarkably similar to newly refined values for the P-O-P bond angle (128.6 degrees) and

Kinetic and binding studies of yeast inorganic pyrophosphatase (EC 3.6.1.1) revealed a regulatory PPi-binding site. Rate vs substrate concentration dependencies were markedly nonhyperbolic in the range of 0.1-150 microM MgPPi at fixed Mg2+ levels of 0.05-10 mM provided that the
Imidodiphosphate (the pyrophosphate analog containing a nitrogen atom in the bridge position instead of oxygen) is a potent inhibitor of family II pyrophosphatases from Streptococcus mutans and Streptococcus gordonii (inhibition constant Ki approximately 10 microM), which is slowly hydrolyzed by
