Dendrogram of 1-aminocyclopropane-1-carboxylate (ACC) deaminase. The tree topology was obtained by neighbor-joining analysis of protein sequences in MEGA 7, previously aligned by CLUSTALW. Reference protein sequences were obtained from NCBI database (cutoff of 86%) and sequence from Serratia sp. M24T3 is indicated in bold. The numbers indicate the percentages of bootstrap sampling, derived from 1000 replications; values below 70% are not shown. Symbol (●) indicates node branches conserved when the tree was reconstructed using the maximum likelihood algorithm. Scale bar 10 inferred nucleotide substitutions per 100 nucleotides. SQ, sequence(s)
