Clostridium scindens American Type Culture Collection 35704 is capable of converting primary bile acids to toxic secondary bile acids, as well as converting glucocorticoids to androgens by side-chain cleavage. The molecular structure of the side-chain cleavage product of cortisol produced by C. scindens was determined to be(More)
PRINTS is a compendium of protein motif fingerprints derived from the OWL composite sequence database. Fingerprints are groups of motifs within sequence alignments whose conserved nature allows them to be used as signatures of family membership. Fingerprints inherently offer improved diagnostic reliability over single motif methods by virtue of the mutual(More)
We have proposed that the lateral inequality of auxin associated with the phototropic response is a consequence of a light-induced impairment of basipolar transport of the hormone. If this is so, the dose-response curve for photoinhibition of auxin transport should resemble that for phototropism. Further, the wavelength dependencies of the transport and(More)
Impaired chloroplast function is responsible for nearly two-thirds of the inhibition of net photosynthesis caused by dark chilling in tomato (Lycopersicon esculentum Mill.). Yet the plant can eventually recover full photosynthetic capacity if it is rewarmed in darkness at high relative humidity. As a means of identifying potential sites of chilling injury(More)
The pattern of protein synthesis in roots of 3-day-old maize seedlings (Zea mays L.) is rapidly and dramatically altered when the incubation temperature is raised from 25 to 40 degrees C. One-dimensional sodium dodecyl sulfate gels reveal that although synthesis of the proteins observed at 25 degrees C continues at 40 degrees C, a new set of ;heat shock(More)
