dimer
heterotetramer
-
2 * 52500 + 2 * 46000, sucrose gradient sedimentation of glutamyl-tRNA reductase preincubated with glutamate-1-semialdehyde aminotransferase. Both enzyme also co-precipitate in immunoprecipitation experiments
homodimer
monomer
additional information
-
2 * 52500, sucrose gradient sedimentation compared to calculation from sequence
dimer
-
2 * 48448, homodimer with an extended structure, electrospray ionization mass spectrometry
dimer
2 * 49000, gel-filtration in presence of 5% glycerol
-
2 * 50000, probably enzyme has an overall V shape that makes the protein migrate slower in gel permeation chromatography
GluTR consists of three domains: an N-terminal catalytic domain, an NADPH-binding domain, and a C-terminal dimerization domain
additional information
-
the enzyme has three functional domains: the GluTR N-terminal domain (101-259), the NAD(P)-binding Rossman fold domaiin (266-422), and the GluTR dimerization domain (425-534)
