Patent number: 8998036Abstract: A dispenser including a base unit with an actuation mechanism for dispensing liquid and a refill unit insertable into the base unit in an inverted configuration with its outlet lowermost for the supply of liquid to the base unit. The refill unit includes an annular wall projecting into the refill unit and defining an outlet from the refill unit, the annular wall being closable at its innermost end by a valve element biased onto the annular wall. The base unit includes a hollow spigot and an annular seal surrounding and spaced from the top of the spigot whereby insertion of the refill unit into the base unit causes the spigot to enter the annular wall and to lift the valve element from the annular wall to define a flow path from the refill unit, and the annular seal to seal between the spigot and the annular wall.Type: GrantFiled: November 22, 2013Date of Patent: April 7, 2015Assignee: Reckitt & Colman (Overseas) LimitedInventors: Xianzhi Zhou, Dong Xiao You, Christopher Leonard Padain, Jacobus Simon Petrus Van Diepen

Patent number: 6953577Abstract: Methionine aminopeptidases catalyse the co-translational removal of amino terminal methionine residues from nascent polypeptide chains. A newly-discovered enzyme, designated methionine aminopeptidase type-3 (MetAP-3), has a substrate specificity which is similar to MetAP-1 and MetAP-2, although it is not inhibited by fumagillin, an irreversible inhibitor of MetAP-2. MetAP-3 also preferentially localizes to mitochondria, unlike MetAP-1 and MetAP-2, which accumulate in the cytoplasm. One embodiment of the present invention relates to human cDNAs encoding polypeptides comprising MetAP-3. Other embodiments of the invention relate to nucleic acid molecules derived from these cDNAs, including complements, homologues, and fragments thereof, and methods of using these nucleic acid molecules, to generate polypeptides and fragments thereof.Type: GrantFiled: November 19, 2002Date of Patent: October 11, 2005Assignee: Pharmacia CorporationInventors: Carolyn J. Sympson, Rajeev Aurora, Stanton B. Dotson, Ronald B. Frazier, Cynthia L. Woods, Hamideh Zakeri, Xianzhi Zhou
