Abstract

The invention provides peptides having cellulase activity and exhibiting at least 40 % amino acid identity in the primary structure with the amino acid sequence shown in one of SEQ ID NO.'s 1, 2, 3 and 4, or comprising a series of at least 8 contiguous amino acids of the amino acid sequence shown in or derived from SEQ ID NO.'s 1-7. Said peptide corresponds to a nematodal peptide especially of a sedentary nematode (such as a cyst nematode or root-knot nematode) or part thereof. Antibodies against such peptides are valuable crop-protecting agents. Furthermore provided are nucleotide sequences encoding these peptides and expression systems comprising at least such a nucleotide sequence. The enzymic peptides are useful in the protection of plants against parasitic nematodes, and in the food and beverage industry, in paper or clothing industry or in waste treatment.

Feeding cells of root-knot ncmatodcs arc so-called giant cells Juveniles of Meloidogvnc migrate interccllularly in the root to the region of c ell differentiation and locate cells in the vascular c\ Under of the stele The luvcnilcs inicct st \ l t secretions into five to seven cells to transform these cells into specialised feeding sites called giant-cells The multinucleate giant cells become the permanent feeding site toi the parasite throughout its life-cycle Giant cell formation is one of the most complex responses elicited in plant tissue by any parasite Cells parasitised by juveniles undergo repeated division of their nuclei without cell division. Each host cell fed upon increases dramatically in size, the central vacuole diminishes in size, the c\ toplasm increases in volume and density, and cell wall ingrowths form, giving the cells a phenotype similar to that of transfer cells Giant cells are induced and maintained in susceptible hosts only by the feeding activities of Meloidogvnc species Stvlet secretions of root-knot ncmatodcs regulate specific host genes affecting protein synthesis nuclear division cell grow th and differentiation and cell w all synthesis.

Cellulasc containing enzv e preparations can be applied:
- in treating ccllulosic fibres to impiove colour and feeling and various other properties. while preventing a lowering in strength of the ccllulosic fibres ( 'loss in w eight treatment" or "stone-free stone-washed process"), as described m WO 94/19528):
- as additive in detergents tor clothing, acting only on the non-crvstallinc region to remove soils and not having an effect of improving colour or feeling of the ccllulosic fibre (see also WO 94/19528); - as additive to feed for domestic animals to more effectively utilise the nutritive components, thus improving feed growth and feed conversion, as described in EP-A- 674843;
- for increasing the filtration rate of beer by degrading ccllulosic fibres;
- for clarification of fruit luiccs and in vegetable processing; - as a bread improver and in bakery applications;
- as a modifier for cellulose for use in dietary food, clinical foods and medicaments;
- for waste water treatment in the pulp and paper industry and in the starch industry; the cellulase assists in removing cellulose residues and also facilitates drainage in paper making and deinking of paper (see WO 94/00578 and WO 96/195 9).

The homogenatc was ccntπtuged for 5 mm. at 14.000 rpm (16.000 x g), and the supernatant and the pellet underneath the fat layer were collected. Shortly before use 1/3 sample volume of 4x SDS-sample buffer (240 mM Tris-Cl (pH 6.8), 40% glycerol, 8% SDS, 0.1 % bromophenol blue. 20 % 2-mcrcaptoethanol) was added, the sample was heated for 3 min at 100 °C and centrituged tor 5 mm. at 14.000 rpm ( 16.000 x g). The overlaying supernatant was used in the preparativ e purification. Purification of proteins

To establish which proteins have cellulasc activity in second stage juveniles (J2s) of G. rosioduensis and H glyctnes and in collected salivary secretions of J2s of G. rostochiensi.s and thus with the gene cloned as described in examples 1 and 2, to test the cellulasc activity of these cloned and hcterologously expressed proteins malE::GR-ENGl and malE::GR-ENG2 (example 3) and to assess the presence of cellulases in J2s of Meloidogvnc incognua and Globoderci labacum. homogenates were prepared in 50 mM Na-phosphate buffer pH 7.2 and subjected to elcctrophoresis on a 10% polvacrylamidc gel containing 20 μg per ml bovine serum albumin. Samples were prepared with a sample buffer having a final SDS concentration of 0.4% while reducing agent was omitted.

To test the inhibiting capacity of MGRs 48. 49. 56, 59 and 60 they were mixed with the hetero- logously expressed proteins MalE::/GR-ENG l and Mali: 'GR-ENG2 Thereto. 4 μl of a 1 mg/ l solution in PCA buffer of each of the antibodies w as mixed with 4 μl of a 1 mg ml (ENG1) or 0.4 mg/ml (ENG2) solution of each of the fusion proteins. As controls PCA buffer, the aspecific anti-cmyc monoclonal antibody 9E10 (in a 1 mg ml concentration) and cellulasc tτom Λspergtllus mgei in a 25 ng/ml concentration were used. The results are shown in figure 7 and in the table below. It was shown that MGR60 inhibited MalE::/GR-ENGl in this set up to about 50% of its activity.
