A structural model of Bacillus subtilis cytochrome c-550 has been built based upon hydropathy analysis, sequence alignment, homology modeling, and energy minimization. The model has a single transmembrane alpha-helix and a water-soluble domain folded around covalently attached heme C. Physical measurements on purified, recombinant cytochrome c-550 have been… (More)
Two new apianen lactones, named as guanyeliaoine I (1) and guanyeliaoine II (2), have been isolated along with seven known compounds from Polygonum perforliatum L. (Chinese name "Guanyeliao", Berberidaceae). Their structures were deduced on the basis of spectral data and chemical methods.
Two new ent-kaurenoids,19-acetoxyl-ent-3beta,17-dihydroxykaur-15-ene (1), 19-acetoxyl-ent-3beta-hydroxykaur-15-en-17-al (2), together with seven known ent-kaurenoids: ent-kaur-16-en-19-al (3), ent-kaur-16-en-19-oic acid (4), ent-kauran-16beta,17-diol (5), ent-15beta, 16beta-epoxy-17-hydroxykauran-19-oic acid (6),19-acetyl-ent-3beta-hydroxyl-kaur-16-ene (7),… (More)
