BADH — Beta vulgaris subsp. vulgaris

Summary

BVRB_5G112650 (symbol BADH) in sugar beet (Beta vulgaris subsp. vulgaris) on chromosome 5 encodes an aldehyde dehydrogenase domain-containing protein with betaine-aldehyde dehydrogenase (NAD+) activity, 4-trimethylammoniobutyraldehyde dehydrogenase activity, and gamma-guanidinobutyraldehyde dehydrogenase (NAD+) activity, along with Na+ and K+ ion binding and protein homodimerization activity. The gene is associated with glycine betaine and betaine biosynthesis, cellular detoxification of aldehydes, and response to salt and salinity stress. It is linked to flavonoid and chlorophyll content. The protein localizes to the cytosol. Studies of related genes in other species connect the family to additional aldehyde dehydrogenase activities (EC 1.2.1.47, 1.2.1.54, 1.2.1.19, 1.2.1.8).
