CC         Evidence={ECO:0000255|HAMAP-Rule:MF_00627};
CC       Note=Binds 2 Zn(2+) ions per subunit. {ECO:0000255|HAMAP-
CC       Rule:MF_00627};
CC   -!- PATHWAY: Amino-acid degradation; L-threonine degradation via oxydo-
CC       reductase pathway; glycine from L-threonine: step 1/2.
CC       {ECO:0000255|HAMAP-Rule:MF_00627}.
CC   -!- SUBUNIT: Homotetramer. {ECO:0000255|HAMAP-Rule:MF_00627}.
CC   -!- SUBCELLULAR LOCATION: Cytoplasm {ECO:0000255|HAMAP-Rule:MF_00627}.
CC   -!- SIMILARITY: Belongs to the zinc-containing alcohol dehydrogenase
CC       family. {ECO:0000255|HAMAP-Rule:MF_00627}.
