Version History for M0127
Version 2.0 => Created
Version 2.4 => The electron acceptor/donors were incorrectly identified as ferrocytochrome c3 and ferricytochrome c3. These have now been renames to reduced ferredoxin and oxidised ferredoxin. An overall comment was added to the effect that the MACiE direction is the opposite to that cited by the EC number, but that the reaction is bi-directional and will take either 2H+ + 2e- → H2 OR H2 → 2H+ + 2e- Other notes: This type of hydrogenase may utilise either ferri- ferro cytochrome or ferredoxin as the acceptor. The dithiolate ligand is also more likely to be aza-dithiolate (S-CH2-NH-CH2-S) and the iron-sulfur clusters have been labelled with their correct PDB HET groups. It has also been explicitly noted that the proton relay chains in steps 1 and 2 is only tentatively identified and have been greyed out in the images.
Version 2.5 => Steps 1 and 2 had incorrect manual bond changes due to long proton relay chains. This has been fixed.
