L-arabinose
L-ribulose
the Bacillus licheniformis L-arabinose isomerase shows a high degree of substrate specificity for L-arabinose. The conserved amino acid Y333 in the substrate binding pocket of the wild-type L-AI is important for the catalytic efficiency, other putative catalytic residues are E306, E333, H350, and H450
