Phylogenetic analysis of l-asparaginase produced by Stenotrophomonas maltophilia as determined by Maximum Likelihood method. Non redundant amino acid sequences of l-asparaginases retrieved from NCBI databases with similarities more than 56% were aligned against the query sequence (l-asparaginase of Stenotrophomonas maltophilia) and used for the tree construction. Additional file 1: Table S1 shows query coverage, E value, percent identity and accession numbers of amino acid sequences of l-asparaginases for the tested bacterial species as revealed by NCBI databases
