Fig. 2From: Bacillus aryabhattai TFG5-mediated synthesis of humic substances from coir pith wastesHomology model of the TryB of B. aryabhattai TFG5. TyrB was predicted using the crystal structure of B. megaterium (3NM8) (a). There were three Cu ligands in the model (each indicated by a sphere), each of which had contact with His residues and the Phe residue (b)Back to article page
