Amino acid alignments with GtrA and GtrB proteins. (A) Translation of 242 coding sequence (NCBI reference sequence WP_012845545) aligned with GtrB proteins from Shigella phage SfII (NCBI Protein accession number YP_008318506 [52]), E. coli K-12 (NCBI Protein accession number P77293 [53]), B. subtilis CsbB (NCBI Protein accession number Q45539 [54]) and Synechocystis sp. strains (NCBI Protein accession number Q55487 and Protein Data Bank number 5EKP [25]). Conserved motifs DXD and DXSXD are underlined, and residues affecting activity in 5EKP are marked with a #. (B) Translation of the 241 coding sequence (NCBI reference sequence WP_004896037) aligned with GtrA family proteins from Shigella phage SfII (NCBI Protein accession number YP_008318507 [52]) and E. coli K-12 (NCBI Protein accession number P77682 [53]). Black, dark gray, and light gray indicate 100%, 80%, and 60% homology, respectively.
