Variation in nucleotide composition of the acceptor arms of cyanobacterial tRNAs. Canonical tRNA possesses seven nucleotides in the acceptor arm. However, in a few cyanobacterial species, the acceptor arm was found to be absent, while in others, the acceptor arm contained four, six or eight nucleotides. In Pseudanabaena sp. PCC 7367 (gene id: 2504679288), the acceptor arm was found to be absent, whereas Fischerella sp. PCC 9431 (gene id: 2512980262) contained four and Rivularia sp. PCC 7116 (gene id: 2510091557) contained six nucleotides.
