Research Abstract |
We were trying to co-crystallize the complex of the PepTSo and antibody. Furthermore we tried to generate antibodies against PEPT homologues, one homologue was from Streptococcus thermophilus (PepTSt) and two were from Arabidopsis thaliana (PTR1 and PTR2). As we generated antibodies against PepTSo, we were successful to produce some antibodies against three homologues. These antibodies recognized conformational epitope of the PEPT homologues. On initial screening by vapor diffusion method, the complex of the PepTSt and this antidody conformed crystals. The crystals were diffracted at about 3.5 angstrom. We are now proceeding the functional and structural analyses.
