In order to get the exact carbohydrate/cellulose binding domain-family of CM10 we translated the given DNA-sequence into amino acids and used the NCBI [http://blast.ncbi.nlm.nih.gov/Blast.cgi?PROGRAM=blastp&BLAST_PROGRAMS=blastp&PAGE_TYPE=BlastSearch&SHOW_DEFAULTS=on&LINK_LOC=blasthome Basic Local Alignment Search Tool]. The alignment the investigation showed was not a carbohydrate binding domain of any kind, but the Xylanase/Glycosyl hydrolase domain of the ''xyn10A'' gene itself (Figure 1).

iGEM Bielefeld-Germany 2012

We ordered the C. josui CM10 (Cellulose-binding motif from C. josui xyn10A gene) of the iGEM 2010 Osaka University to compare it to other cellulose binding domains (BBa_K863101; BBa_K863111) in our project.

In order to get the exact carbohydrate/cellulose binding domain-family of CM10 we translated the given DNA-sequence into amino acids and used the NCBI [http://blast.ncbi.nlm.nih.gov/Blast.cgi?PROGRAM=blastp&BLAST_PROGRAMS=blastp&PAGE_TYPE=BlastSearch&SHOW_DEFAULTS=on&LINK_LOC=blasthome Basic Local Alignment Search Tool]. The alignment the investigation showed was not a carbohydrate binding domain of any kind, but the Xylanase/Glycosyl hydrolase domain of the xyn10A gene itself (Figure 1).

Figure 1:Protein-BLAST of translated-BBa_K392014-sequence

To get sure, we looked up the [http://www.ncbi.nlm.nih.gov/nuccore/AB041993 xyn10A gene of C.josui] and searched the ORF in the same way for conserved domains. The protein search (Figure 2) showed two carbohydrate binding modules within the open reading frame and the glycosyl hydrolase domain. This result confirmed that the iGEM 2010 Osaka University had cloned the wrong domain of the xylanase-protein. The cellulose binding modul (CBM9_like_1) up-stream of the glycosyl hydrolase domain would have been of use for our project and is the protein-domain we would have expected by the title of this BioBrick.

Figure 2:Protein-BLAST of the original [http://www.ncbi.nlm.nih.gov/nuccore/AB041993 xyn10A gene of C.josui]

To match the result with the given DNA-sequence we programmed the region of every domain into a clonemanager-file of the Clostridium josui xynA' gene for xylanase A and aligned it with the BBa_K392014. The alignment (Figure 3) revealed the same connection of gene and BioBrick as before.

Figure 3:Graphical alignment of BBa_K392014 and the [http://www.ncbi.nlm.nih.gov/nuccore/AB041993 xyn10A gene of C.josui]

To be absolutely sure we got the BBa_K392014 sequenced, hoping that just a wrong sequence was posted into the registry. But the results confirmed 100% alignment with the given sequence of this part.
