Subunits associate or dissociate reversibly as a function of pH and ionic strength. The native decameric form is formed by the cyclic association of five dimers. Its overall appearance is that of two stacked pentameric rings. Higher aggregates result from the linear stacking of decamers to form rodlike particles of indefinite length -, 37293 4.1.1.18 ? x * 85000, SDS-PAGE -, 727766 4.1.1.18 decamer - 748418 4.1.1.18 decamer 10 * 80000, SDS-PAGE 37299 4.1.1.18 decamer 10 * 81000, recombinant His-tagged wild-type and mutant T88S, SDS-PAGE 747396 4.1.1.18 decamer the protein is an oligomer of five dimers that associate to form a decamer, X-ray crystallography 714832 4.1.1.18 decamer x-ray crystallography 690269 4.1.1.18 dimer - 748418 4.1.1.18 dimer 2 * 42000, SDS-PAGE 654982 4.1.1.18 dimer 2 * 44000, SDS-PAGE 37290 4.1.1.18 dimer 2 * 76500, SDS-PAGE -, 728013 4.1.1.18 heptamer 7 * 79000, SDS-PAGE -, 37300 4.1.1.18 hexamer isozyme TT1465, crystallization data -, 666850 4.1.1.18 homodecamer - 749366 4.1.1.18 homodecamer 10 * 81000, X-ray crystallography 716768 4.1.1.18 homodecamer a pentamer of homodimers, 10 * 82000, recombinant His6-tagged wild-type enzyme, SDS-PAGE -, 747369 4.1.1.18 homodimer 2 * 44000, recombinant His-tagged enzyme, SDS-PAGE 749097, 749101 4.1.1.18 monomer 1 * 95000, SDS-PAGE 37297 4.1.1.18 additional information a mixture of dimers (about 158 kDa) and decamers (about 780 kDa) is present for the enzyme at pH 7.5. Decamers are dominant for AsLdc, dependent on the pH: the highest proportion of decamer for AsLdc (78%) is observed at pH 7.5, while it is reduced to 30% and 57% at pH 5.0 and pH 8.5, respectively 748418 4.1.1.18 additional information enzyme interacts strongly with regulatory ATPase variant A, RavA, forming a cage-like structure consisting of two enzyme decamers linked by up to five RavA oligomers. Enzyme activity is not affected by binding to RavA, but complex formation results in stimulation of RavA ATPase activity 665713 4.1.1.18 additional information SrLDC functions as a dimer and each monomer consists of two distinct domains, a pyridoxal 5'-phosphate-binding-barrel domain and a sheet domain.
