Residues at nucleotide-binding pocket are well conserved in ScMreB5. Sequence alignment of ScMreB5 (ScMreB5) with other S. citri MreBs (ScMreB1, ScMreB2, ScMreB3, and ScMreB4), CcMreB, TmMreB, EcMreB, B. subtilis MreB (BsMreB), and yeast actin. Residues involved in ATP hydrolysis (black arrow), K⁺ coordination (black star), and polymerization interface (blue arrow) are marked. Percentage identities of each sequence with ScMreB5 are marked at the end of the sequence alignment.
