    • The invention relates to the production of heterologous polypeptides in a recombinant host cell. More specifically, it relates to the production and secretion of peptides, such as biologically active peptides, that are modified by one or more lantibiotic-synthesizing enzymes. Provided is a nucleic acid construct encoding a polypeptide comprising 1) a non-lantibiotic export signal that is recognized by a non-lantibiotic export system; 2) a lantibiotic leader peptide that is recognized by at least a lantibiotic dehydratase such as LanB and, C-terminally of said export signal and said leader peptide, 3) a peptide of interest containing one or more serine or threonine residue(s) which can be posttranslationally dehydrated by said dehydratase. Also provided is a method for producing a polypeptide in a host cell, comprising providing a host cell with a nucleic acid construct according to the invention and allowing expression and secretion of the encoded polypeptide by said host cell, wherein said host cell comprises at least a dehydratase capable of modifying said encoded polypeptide and a non-lantibiotic export system capable of secreting said modified polypeptide.

    • 1,037,311. Impact pulverizers. K. H. CONLEY, A. J. TENNER and C. C. WALLACE. Jan.29,1963 [Jan. 29,1962], No. 3726/63. Heading B2A. An impact pulverizer comprises a rotor 60 contained in a housing consisting of a member 33 and a hopper 70 releasably secured thereto, material fed to the rotor by a shoot 44 releasably secured to the member 33 being prevented from impinging on the member 33 by means of a liner 50 and a plate 34. The edges of the plate 34 are supported by the liner 50 which has secured thereto sockets 55 engageable by bolts 54 for detachably securing the liner to the member 33. The plate 34 has a collar portion which passes through an aperture in the member 33, the collar portion having peripheral grooves 34e engageable by bolts 47 the upper edge of the collar portion having two cutouts so that by rotating the plate the latter can be released from the bolts. Air under pressure is supplied through a fitting 41 via recessed region 34d to the interior of the housing. The hub of the rotor has mounted thereon a cutter distributor member 58 which comprises a pair of discs provided with projecting blades to break up agglomerative-particles of the input material and a further disc, above the pair of discs, provided with radial grooves to set up centrifugal movement of air. Rows of impacting elements 51 secured to the liner are interspersed with rows of impacting elements 60alpha secured to the rotor. The hopper 70 is detachably secured to the member 33 and the liner 50 by means of bolts 73 and has secured thereto a wall 75, to reduce noise, and a spiral 80 between and/or through the turns of which a cooling fluid is passed. Rotatable lugs 82 screwed into sockets attached to a flange 33a of member 33 are provided with pins 82alpha and 82b to facilitate assembly of the liner and.hopper respectively.-
