  Isolation, partial purification, and characterization of a novel petromyzonol sulfotransferase from Petromyzon marinus (lamprey) larval liver

  摘要：

  We have isolated, partially purified, and characterized the 5alpha-petromyzonol (5alpha-PZ), (5alpha-cholan- 3alpha, 7alpha, 12alpha, 24-tetrahydroxy-) sulfotransferase (PZ-SULT) from larval lamprey liver. Crude liver extracts exhibited a PZ-SULT activity of 0.9120 pmol/min/mg in juvenile and 12.62 pmol/min/mg in larvae. Using crude larval liver extracts and various 5 beta-cholan substrates and allocholic acid there was negligible activity, however, with 5alpha-PZ and 3-keto-5alpha-PZ the SULT activity was 231.5 pmol/min/mg and 180.8 pmol/min/mg respectively. This established that the sulfotransferase of lamprey larval liver extracts prefers (5 alpha) substrates and it is selective for hydroxyl at C-24. PZ-SULT was purified through various chromatography procedures. Partially purified PZ-SULT exhibited a pH optimum of 8.0, a temperature optimum of 22degreesC, and activity was linear for 1h. PZ-SULT exhibited a K-m of 2.5 muM for PAPS and a K-m of 8 muM for PZ. The affinity purified peak PZ-SULT exhibited a specific activity of 2,038 pmol/min/mg. The peak protein upon SDS-PAGE, correlated to an Mw 47 kDa. Photoaffinity labeling with PAP(35)S, specifically crosslinked the 47 kDa protein, further confirming the identity of PZ-SULT. Partial amino acid sequencing of the putative 47 kDa PZ-SULT protein yielded a peptide sequence (M)SISQAVDAAFXEI, which possessed an overall (similar to35-40%) homology with mammalian SULT2B1a.-Venkatachalam, K. V., D. E. Llanos, K. J. Karami, and V. A. Malinovskii. Isolation, partial purification, and characterization of a novel petromyzonol sulfotransferase from Petromyzon marinus (lamprey) larval liver.

  A novel bile alcohol of general formula (I), having an efficacious physiological activity and being specified in the configurations of particularly the 20-, 24- and 25-positions; formula (I) wherein one of the groups R₁ and R₂ represents a group of formula (A) or (B) while the other represents -OH or -H; R₃ and R₄ represent each -CH₂OH, -CH₃ or -CH₂OSO₃Na; or alternatively R₂ and R₃ are combined together to represent -OCH₂-, R₂ and R₄ are combined together to represent -OCH₂-, or R₃ and R₄ are combined together to represent -CH₂OCH₂-; provided that R₃ and R₄ do not represent -CH₃ at the same time and that R₁ represents -OH or -H and R₂ represents the group of formula (A) or (B) when R₃ and R₄ represent -CH₂OH at the same time. A drug containing the bile alcohol, including those wherein R₃ and R₄ in the above formula (I) represent each -H, -CH₂OH, -CH₃ or -CH₂OSO₃Na (except for the case where both R₃ and R₄ represent -H at the same time), and 3α 7α, 12α, 24-tetrahydroxy-5α- or -5β-cholane is efficacious as a cerebral function protective agent, cholagogue, cell activator, microcirculation improver, antiarteriosclerotic agent, antihyperlipemia drug, hepatic function improver, anti-inflammatory drug, antithrombotic drug and hypertensive.
