α-D-Galactose-1-phosphate is an intermediate in the interconversion of glucose and galactose. It is produced from galactose by galactokinase. Galactose-1-phosphate uridyl transferase reversibly catalyzes the conversion of UDP-glucose (Item No. 15602 and galactose-1-phosphate to glucose-1-phosphate and UDP-galactose.

Hereditary Dystonia Overview
The purpose of this overview on hereditary dystonia is to help clinicians determine if an individual has a hereditary dystonia in order to provide information regarding recurrence risk and evaluation of relatives at risk. Goal 1: Describe the clinical characteristics of dystonia. Goal 2: Review the causes of hereditary dystonia. Goal 3: Provide an evaluation strategy to determine the etiology of hereditary dystonia in a proband. Goal 4: Review the differential diagnosis of hereditary dystonia (i.e., non-genetic causes of dystonia). Goal 5: Provide information regarding recurrence risk and evaluation of relatives of a proband with hereditary dystonia who are at risk.
The C-terminal domain of the Salmonella enterica WbaP (UDP-galactose:Und-P galactose-1-phosphate transferase) is sufficient for catalytic activity and specificity for undecaprenyl monophosphate
Two families of membrane enzymes catalyze the initiation of the synthesis of O-antigen lipopolysaccharide. The Salmonella enterica Typhimurium WbaP is a prototypic member of one of these families. We report here the purification and biochemical characterization of the WbaP C-terminal (WbaP(CT)) domain harboring one putative transmembrane helix and a large cytoplasmic tail. An N-terminal thioredoxin fusion greatly improved solubility and stability of WbaP(CT) allowing us to obtain highly purified protein. We demonstrate that WbaP(CT) is sufficient to catalyze the in vitro transfer of galactose (Gal)-1-phosphate from uridine monophosphate (UDP)-Gal to the lipid carrier undecaprenyl monophosphate (Und-P). We optimized the in vitro assay to determine steady-state kinetic parameters with the substrates UDP-Gal and Und-P. Using various purified polyisoprenyl phosphates of increasing length and variable saturation of the isoprene units, we also demonstrate that the purified enzyme functions highly efficiently with Und-P, suggesting that the WbaP(CT) domain contains all the essential motifs to catalyze the synthesis of the Und-P-P-Gal molecule that primes the biosynthesis of bacterial surface glycans.
