tctA_503: large subunit A1 of the tripartite tricarboxylate transporter family

The large subunit A1 of the tripartite tricarboxylate transporter family (tctA_503, 52,98 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(in this case tctA_503), and a small poorly conserved membrane proteine with four putative transmembrane alpha-helical spanner[1]. The strain was purchased from 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:[http://2012.igem.org/Team:TU_Darmstadt/Protocols/mutagenic_PCR mutagenic PCR]) To characterized the structure of the tctA_503 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 N-teminus is with a probability of 98 % in cytoplasmatic. The NCBI Protein BLAST results shows that the tctA_503 subunit A1 belongs to the tctA superfamily. PHYRE2 and I-Tasser server homology modelling did not give a significant result for the structure of the tctA_503 subunit A1.
