dilution inactivates methanol dehydrogenase activity, not reductase activity, sucrose, 20% w/v, stabilizes formaldehyde reductase not methanol dehydrogenase activity, metal ions, such as Fe2+ and Zn2+, do not stabilize methanol dehydrogenase activity, glycerol does not stabilize methanol dehydrogenase activity, dithiothreitol stabilizes reductase, not methanol dehydrogenase activity, storage leads to dissociation | Bacillus methanolicus |
