Dextransucrase from Streptococcus sanguis ATCC 10558 was photolabeled using p-azidophenyl alpha-D-glucopyranoside with an apparent rate constant of inactivation of 1.40 min-1. The dissociation constant for this compound, which acts as an acceptor molecule in the enzymatic reaction, is 90 microM. App
Two alpha-D-glucans, produced from amylopectin by an oral isolate Streptococcus sanguis 1 MC 204, were shown to contain both (1----4) and (1----6) linkages. The first alpha-D-glucan (amyloglucan) was adherent and highly insoluble, and methylation analysis, i.r. spectroscopy, and enzymic analyses sho
