Three children with branched-chain ketoaciduria (maple syrup urine disease) were found to excrete an abnormal amino acid when they were on an artificial diet. This substance was identified as 4-amino-2-(S-cysteinyl)butyric acid with the use of column liquid chromatography, gas chromatography--mass
The organisation of the E1alpha subunit of bovine branched-chain alpha-keto acid dehydrogenase gene was established. c DNA was cloned from Poll Shorthorn x Poll Hereford calves affected with Maple Syrup Urine Disease to identify the mutation responsible for the disease in Poll Shorthorns. Clones
We have cloned cDNAs encoding the E1b-alpha, E1b-beta, and E2b subunits of the bovine and human branched-chain alpha-keto acid complexes. The deduced primary structures indicate that the mammalian E2b contains a lipoyl-bearing, an E3-binding, and an inner core domain that are linked in series by two
