L. lactis IO-1 XylA sequence with residues conserved among 22 group II XylA sequences indicated. The group II xylose isomerase sequences examined were from L. lactis IO-1 (this work), L. lactis 210 (this work), L. lactis B-4449 (this work), L. brevis (GenBank accession no. AF045552), L. pentosus (M57384), S. xylosus (X57599), B. licheniformis (Z80222), B. megaterium Z71474), B. subtilis (U66480), Bacillus sp. strain LW2 (L12967), Thermotoga neapolitana (L38994), Thermoanaerobacter spp. strain (U21678), Thermoanaerobacter thermosulfurogenes (J05650), Thermoanaerobacter saccharolyticum (L09699), Thermoanaerobacter thermosaccharolyticum (M91248), Thermoanaerobacter thermohydrosulfuricus (D00756), Thermoanaerobacter ethanolicus (AF001974), E. coli (X04691), Klebsiella pneumoniae (X61059), Klebsiella aerogenes (Swiss-Prot accession no. P29442), and H. influenzae (GenBank accession no. U32791). Conserved residues are indicated as follows: bold underlined residues, identical for all 22 strains; underlined residues, identical or similar for 20/22 strains; ∗ (above sequence), difference between L. lactis IO-1, 210, and/or B-4449; ↓, conserved S. rubiginosus active site residue, according to Whitaker (50).
