Described herein are novel gene sequences isolated from Trichoderma reesei. Two genes encoding proteins comprising a cellulose binding domain, one encoding an arabionfuranosidase and one encoding an acetylxylanesterase are described. The sequences, CIP1 and CIP2, contain a cellulose binding domain. These proteins are especially useful in the textile and detergent industry and in pulp and paper industry. cip1 cDNA sequence (SEQ ID NO: 1) GACTAGTTCA TAATACAGTA GTTGAGTTCA TAGCAACTTC50 ACTCTCTAGC TGAACAAATT ATCTGCGCAA ACATGGTTCG CCGGACTGCT100 CTGCTGGCCC TTGGGGCTCT CTCAACGCTC TCTATGGCCC AAATCTCAGA150 CGACTTCGAG TCGGGCTGGG ATCAGACTAA ATGGCCCATT TCGGCACCAG200 ACTGTAACCA GGGCGGCACC GTCAGCCTCG ACACCACAGT AGCCCACAGC250 GGCAGCAACT CCATGAAGGT CGTTGGTGGC CCCAATGGCT ACTGTGGACA300 CATCTTCTTC GGCACTACCC AGGTGCCAAC TGGGGATGTA TATGTCAGAG350 CTTGGATTCG GCTTCAGACT GCTCTCGGCA GCAACCACGT CACATTCATC400 ATCATGCCAG ACACCGCTCA GGGAGGGAAG CACCTCCGAA TTGGTGGCCA450 AAGCCAAGTT CTCGACTACA ACCGCGAGTC CGACGATGCC ACTCTTCCGG500 ACCTGTCTCC CAACGGCATT GCCTCCACCG TCACTCTGCC TACCGGCGCG550 TTCCAGTGCT TCGAGTACCA CCTGGGCACT GACGGAACCA TCGAGACGTG600 GCTCAACGGC AGCCTCATCC CGGGCATGAC CGTGGGCCCT GGCGTCGACA650 ATCCAAACGA CGCTGGCTGG ACGAGGGCCA GCTATATTCC GGAGATCACC700 GGTGTCAACT TTGGCTGGGA GGCCTACAGC GGAGACGTCA ACACCGTCTG750 GTTCGACGAC ATCTCGATTG CGTCGACCCG CGTGGGATGC GGCCCCGGCA800 GCCCCGGCGG TCCTGGAAGC TCGACGACTG GGCGTAGCAG CACCTCGGGC850 CCGACGAGCA CTTCGAGGCC AAGCACCACC ATTCCGCCAC CGACTTCCAG900 GACAACGACC GCCACGGGTC CGACTCAGAC ACACTATGGC CAGTGCGGAG1000 GGATTGGTTA CAGCGGGCCT ACGGTCTGCG CGAGCGGCAC GACCTGCCAG1050 GTCCTGAACC CATACTACTC CCAGTGCTTA TAAGGGGATG AGCATGGAGT1100 GAAGTGAAGT GAAGTGGAGA GAGTTGAAGT GGCATTGCGC TCGGCTGGGT1150 AGATAAAAGT CAGCAGCTAT GAATACTCTA TGTGATGCTC ATTGGCGTGT1200 ACGTTTTAAA AAAAAAAAAA AAAAAAAAAA AAAAAAAAAA AAAAAAAAAA1250 AAAAAAAAAA AAAAAAAAAG GGGGCGGCCG C1271
