Definitions

  • the DNA of interest is identified by the expression of the protein it encodes, rather than by going through the tedious tasks of purifying the protein, amino acid sequencing and molecular cloning of o the gene.
  • One technique of expression cloning is a plate assay, wherein a cDNA library is plated onto a medium of a composition which enables screening for positive colonies. Screening for the protein of interest does not require pure protein, only the availability of a suitable assay for the detection of activity. This may be a standard assay if for example, cellulase activity may be detected using an overlay containing carboxymethyl cellulose, followed by visualisation by staining with Congo Red.
  • the nucleic acid sequence of the invention is operably linked to a promoter capable of expressing the sequence.
  • "Operably linked” refers to a juxtaposition wherein the promoter and the nucleic acid sequence encoding the polypeptide or protein are in a relationship permitting the coding sequence to be expressed under the control of the promoter.
  • there may be elements such as 5' non-coding sequence between the promoter and coding sequence.
  • Such sequences can be included in the vector if they enhance or do not impair the correct control of the coding sequence by the promoter.
  • the invention also provides polypeptides encoded by the nucleic acids of the invention.
  • A. niger N400 cultures were grown for 69 and 81 h respectively, as described in s EP-A- 0 463 706 but without yeast extract and with 2% of a crude wheat arabinoxylan fraction instead of oat spelt xylan, after which the mycelium was harvested by filtration and then washed with sterile saline. The mycelium was subsequently frozen in liquid nitrogen after which it was powdered using a Microdismembrator (Braun). Total RNA was isolated from mycelial powder in accordance with the guanidium thiocyanate/CsCI o protocol described in Sambrook et al. (1 989), except that the RNA was centrifuged twice using a CsCl gradient.
  • the recombinant Uni-ZAP XR clones containing A. niger cDNA were converted to Bluescript phagemids using superinfection with the filamentous helper phage EXASSIST'TM and E.coli SOLR strain which are included in the cDNA synthesis kit from Stratagene, according to the manufacturer's instructions.
  • a glycerol stock containing about 100 colonies per vl of suspension was stored at -80°C.
  • Cells are plated in an overlay of 5 ml containing about 200 colonies per plate. The overlay is kept at 50°C and contains 2 x TY, 0.2% CMC, 0.75% agar and 100 ⁇ g ampicillin per ml. Plates are covered with 5 ml 0.5% agarose, 0.2% CMC and 100 ⁇ g ampicillin per ml kept at 50°C.
  • Example IV.1 Screening for endo-xylanase activity.
  • the method is similar to that used for cellulase-producing colonies in Example III.
  • the bottom layer contains 2 x TY, 1 .5% agar and 100 ⁇ g ampicillin per ml.
  • Cells are plated out in an overlay containing 2 x TY, 0.2 % oat spelt xylan (Sigma X-0627) 0.75 % agar and 100 ⁇ g ampicillin per ml.
  • the top layer contains 0.5% agarose, 0.1 % RBB-xylan (Sigma M501 ) and 100 ⁇ g ampicillin per ml in 25 mM phosphate buffer pH7.4.
  • the plasmid library was also plated on minimal medium plates containing 2% oat spelt xylan. After two days at 37°C some colonies gave halos, indicating the production of endo-xylanase. Other colonies gave rise to precipitation rings around the colonies. Five of the latter colonies were partially sequenced. They were similar to the arabinoxylan degrading cDNA whose isolation is described in pending application EP 94202442.3. A colony containing an A. niger axdA cDNA was deposited at the CBS on 3 August 1995 under CBS 592.95. The DNA sequence of the insert is as shown in SEQ ID No. 9, together with the amino acid sequence it encodes.

Abstract

Cette invention concerne un procédé d'identification d'un fragment d'ADN codant une protéine à analyser. D'après ce procédé, on crible une banque d'ADNc, se présentant sous forme de cellules hôtes bactériennes transformées par de l'ADN obtenu dans un organisme eucaryote capable de produire ladite protéine, ceci afin de déceler l'expression de ladite protéine à l'aide d'un test qui permet de révéler sa présence. Ce procédé se caractérise par le fait que le criblage des cellules hôtes se fait une fois que l'ADN de transformation est devenu partie d'un plasmide. La banque d'ADNc provient de préférence d'un organisme eucaryote. Il est souhaitable que cet organisme eucaryote soit un champignon ou une cellule de levure, de préférence une espèce Aspergillus, et idéalement, un élément du groupe Aspergillus niger. Les enzymes ainsi criblés consistent, de préférence, en des enzymes présentant une activité de dégradation d'arabinoxylane, d'endoxylanase ou de cellulase.
