ah the YAML conversion & validation tests are failing because apparently MAR07799 was the only reaction that ENSG00000071553 (ATP6AP1) was associated with

According to this paper, which seems to have been the first to characterize ATP6AP1's role in the assembly of the V-type ATPase complex, "missense disease mutations in ATP6AP1 cause reduced V-ATPase function by affecting its folding and assembly." So it should probably be added to the GPR of MAR00080.

The GPR of MAR00080 currently looks like this:

So it looks like all the genes encoding the subunits of the V0 complex are grouped together in the first bit and the genes encoding the subunits of the V1 complex are in the second bit. The graphical abstract of the paper I linked earlier shows ATP6AP1 attached to the bottom of the V0 complex, so I'm just gonna add "and ATP6AP1" to each of those groups

This PR has been automatically tested with GH Actions. Here is the output of the macaw test:

Starting dead-end test...
 - Found 1373 dead-end metabolites.
 - Found 1129 reactions incapable of sustaining steady-state fluxes in either direction due to these dead-ends.
 - Found 2077 reversible reactions that can only carry steady-state fluxes in a single direction due to dead-ends.
Starting duplicate test...
 - Skipping redox duplicates because no redox_pairs and/or proton_ids were provided.
 - Found 447 reactions that were some type of duplicate:
   - 0 were completely identical to at least one other reaction.
   - 13 involve the same metabolites but go in the opposite direction or have the opposite reversibility as at least one other reaction.
   - 447 involve the same metabolites but with different coefficients as at least one other reaction.

A more detailed output from this test run is also committed to data/macawResults/macaw_results.csv.

Note: In the case of multiple test runs, this post will be edited.

The reaction stochiometry was incorrect. ATPase is a rotary motor protein, where a full turn of the rotating part of the enzyme comes to the cost of 3 ATP. Then, the number of c-subunits is determining how many protons are pumped per full turn. The structure in this paper shows The Vo complex comprises the c-ring of c(1)-c(9) and c″, which gives a total of 10 c-subunits.

Together, that makes that 3 ATP are hydrolysed to transport 10 H+ into the lysosome. However, ATP hydrolysis also releases 1 H+ per ATP (see for instance reaction MAR03964), so that the number of H+ in the cytosol only decreases by 7. The resulting equation is then:

3 ATP[c] + 3 H2O[c] + 7 H+[c] => 3 ADP[c] + 3 Pi[c] + 10 H+[l].
