Amino acid multiple alignments. Hydrophobic amino acids are represented in red (A, I, L, M, F, W, V, P). Polar amino acids are represented in green (N, Q, S, T, C, G, H, Y). Positively charged amino acids are represented in magenta (K, R). Negatively charged amino acids are represented in blue (D, E). CTX-M-1, CTX-M-2, CTX-M-8, CTX-M-9, and CTX-M-25 have 291 amino acids, while CTX-M-151 has 304 amino acids. “*” represents fully conserved residues, “.” indicates conservation between groups of strongly similar properties and “:” indicates conservation between groups of weakly similar properties.
