Title: PROTEASE ACIDE THERMOSTABLE DU $i(SULFOLOBUS ACIDOCALDARIUS), ET GENE
Inventor: TANG JORDAN J N
IPC: C12N15/09
Filed: 1990-02-22
Abstract: Une protéase thermostable très acide, que l'on a appelée thermopsine, a été purifiée jusqu'à homogénéité à partir du milieu de culture du Sulfolobus acidocaldarius au cours d'un procédé en cinq étapes comprenant des chromatographies sur colonne sur DEAE-Sépharose CL-6B, phényl-Sépharose CL-4B, Séphadex G-100, MonoQ (FPLC), et filtration par gel (HPLC). L'enzyme est une chaîne polypeptidique simple ayant une activité protéolytique sur une plage du pH de 0 à 11 à des températures comprises entre 0 et 100°C, avec une activité maximale approximativement avec un pH de 2 et une température de 90°C. Des anticorps contre la thermopsine ont été préparés. Grâce à des études utilisant divers inhibiteurs de protéase aspartique, des inhibiteurs de thiol et de métalloprotéase et des inhibiteurs de protéase de sérine, on a pu déterminer que, bien que le site actif de la thermopsine soit similaire à certaines protéases aspartiques, il n'est pas identique à celui d'autres protéases aspartiques. La thermopsine hydrolyse les liaisons suivantes: Leu-Val, Leu-Tyr, Phe-Phe, Phe-Tyr, et Tyr-Thr, indiquant par là que la spécificité de la thermopsine est semblabe à celle de la pepsine pour les gros restes hydrophobes des deux côtés de la liaison scissile. De plus, la thermopsine est résistante à l'inactivation des détergents, la protéine gardant son activité protéolytique même en présence de fortes concentrations de sulfate dodecyle de sodium.

Abstract: The invention relates to a process for the (co-)polymerisation of alpha-olefins in a gas phase, in a fluidised and/or mechanically agitated bed reactor. The process is carried out with the help of a composition comprising (a) 100 parts by weight of an alpha-olefin prepolymer powder containing a Ziegler-Natta type catalyst or a heat activated chromium oxide catalyst and an organometallic compound of a metal of Groups I to III of the periodic Table of Elements, and (b) from 0.1 to 20 parts by weight of a pulverulent inorganic substance consisting of very fine particles, free from transition metal compound and chemically inert to the constituents of the (co-)polymerisation. The invention also relates to the composition comprising the prepolymer powder and the pulverulent inorganic substance. The advantage of using such a composition consists of operating a gas phase (co-)polymerisation of alpha-olefins at higher temperatures.

Abstract: In an exhaust system of a combustion engine which contains a particle filter (12) and a burner (11) for regeneration of the filter, an arrangement is proposed, in which the fuel for the burner is oxidised in a number of stages. The fuel is first sprayed with atomising air (53) into a mixing pipe (41) and there ignited and mixed with primary combustion air (40). A part of the still uncombusted fuel is combusted by residual oxygen from exhaust (16a) entering into the combustion chamber (21). Finally the remainder of the uncombusted fuel is completely combusted on leaving the combustion chamber (21) by the residual oxygen of the exhaust (16b) flowing around the flame pipe (15). The burner operation is regulated during the regeneration phase by changing the quantity of fuel, the primary air quantity being kept constant. <IMAGE>

Abstract: Described is a dry kava extract with a total kavalactone content of at least 50 % by wt. and a flavokavin content of at the most 0.3 % by wt. The extract is readily soluble in water and has high bio-availability following oral administration. In order to increase the kavalactone content and decrease the flavokavin content of the extract, a method is proposed in which the raw extract is brought into solution and the flavokavin content reduced by cold precipitation or by solvent partition, after which the solution is concentrated to dryness. The dry extract can be used to prepare drugs.
