Analysis of the relationships between the nine TTT family proteins located in the largest tandem array found in Rhodoplanes sp. Z2-YC6860. (a) Similarity matrix for amino acid sequences between proteins belonging to the nine-gene cluster. With the exception of RHPLAN_16830, which shared highest identity with RHPLAN_10480 (53.1 %), the remaining shared similarities were below 50 %. (b) Representation of highest identity for individual proteins in the cluster through blastp searches against 2323 bacterial genomes. The arrows represent the highest shared identity for each protein. Of the nine proteins in the array, only three members shared highest amino acid identity with other members of the same array, while four members shared highest identity with RHPLAN_29570, located elsewhere in the same genome. Two members were more similar to the TTT SBP ANW05692.1_3832 from Bradyrhizobium icense than to any gene inside the genome of Rhodoplanes sp. Z2-YC6860.
