Test change definitions for L-cysteine

[ontobot]

The following commands were executed:
* change definition of GO:0000008 from 'OBSOLETE. A small disulfide-containing redox protein that serves as a general protein disulfide oxidoreductase. Interacts with a broad range of proteins by a redox mechanism, based on the reversible oxidation of 2 cysteine thiol groups to a disulfide, accompanied by the transfer of 2 electrons and 2 protons. The net result is the covalent interconversion of a disulfide and a dithiol.' to 'OBSOLETE. A small disulfide-containing redox protein that serves as a general protein disulfide oxidoreductase.
