Obsoletion notice: some secondary active transporter activity terms

[pgaudet]

Dear all,

The proposal has been made to obsolete:

GO:0015322 | secondary active oligopeptide transmembrane transporter activity GO:0015328 | cystine secondary active transmembrane transporter activity GO:0015351 | bilirubin secondary active transmembrane transporter activity GO:0015400 | low-affinity secondary active ammonium transmembrane transporter activity GO:0000227 | oxaloacetate secondary active transmembrane transporter activity GO:0015324 | peptide-acetyl-CoA secondary active transmembrane transporter activity GO:0022897 | proton-dependent peptide secondary active transmembrane transporter activity GO:1901680 | sulfur-containing amino acid secondary active transmembrane transporter activity

The reason for obsoletion is that we would like to specify transporter mechanisms; and secondary active can be one of several mechanisms. These terms have no references, no cross references, and no annotations, so we cannot assign a mechanism.

Annotation review is here: https://github.com/geneontology/go-annotation/issues/5209 (note that the review also contains terms with annotations, these are not candidates for obsoletion)

You can comment on the ticket: https://github.com/geneontology/go-ontology/issues/27771

Thanks, Pascale
