tctA_505: large subunit A2 of the tripartite tricarboxylate transporter family
The large subunit A2 of the tripartite tricarboxylate transporter family (tctA_505, 52,99 kDa) was isolated from Comamonas testosteroni KF-1. The tripartite tricarboxylate transporter system consists of three different proteins: a periplasmatic solute binding receptor, a membrane protein with 12 putative transmembrane alpha-helical spanners (in this case tctA_503), and a small poorly conserved membrane proteine with four putative transmembrane alpha-helical spanners[1].The strain was purchased from Leibniz Institute DMSZ-German Collection of Microorganism and Cell Cultures (DMSZ no. 14576). The original sequence contains a Pst1 recognition site. To eliminate this recognition site a directed-site mutagenic PCR was performed. (For more datails: link zu dem PCR protokoll und dem Labjournal, wo isolations PCR beschrieben wird) To characterized the structure of the tctA_505 bioinformatic tools like Protein Homology/anologY Recognition Engine V 2.0 (PHYRE2), I-TASSER servers, and TMHMM was used. The TMHMM predicted a transmembrane protein with 11 alpha-helical spanners (Fig. 1).The NCBI Protein BLAST results shows that the tctA_505 subunit A2 belongs to the tctA superfamily.Phyre2 an I-Tasser server homology modelling did not give a significant result for the structure of the tctA_505 large subunit A2. ]]
