The reason for obsoletion is that these represent specific substrates of GO:0016906 sterol 3-beta-glucosyltransferase activity. There are 5 manual annotations to these terms, by dictyBase and TAIR, see https://github.com/geneontology/go-annotation/issues/5281.
EDITED
Dear all,
The proposal has been made to obsolete
GO:0051507 beta-sitosterol UDP-glucosyltransferase activity GO:0051506 ergosterol UDP-glucosyltransferase activity GO:0051508 stigmasterol UDP-glucosyltransferase activity GO:0051509 tomatidine UDP-glucosyltransferase activity GO:0102203 brassicasterol glucosyltransferase activity GO:0102205 cholesterol alpha-glucosyltransferase activity GO:0102202 soladodine glucosyltransferase activity GO:0102925 solanine UDP-galactose galactosyltransferase activity GO:0102926 solanidine glucosyltransferase activity
