Alignment of amino acid sequences of LipA from Acremonium alcalophilum with other lipases and feruloyl esterase from various microorganisms. The amino acid sequence of LipA was compared with the lipase amino acid sequences of Aspergillus niger (An_lipase), Thermomyces lanuginosus (Tl_lipase); and ferulic acid esterase amino acid sequence of Aspergillus niger (An_FAE). Identical residues among the four enzymes are marked with asterisks. Residues with conserved and semiconserved substitutions are indicated with colons and dots, respectively; the conserved GXSXG motif and putative residues of the catalytic triad are underlined in red.
