Abstract
These isolates were tested for production of extracellular Glucosyltransferase (GTF) through determination of their enzyme specific activity. All isolates were able to produce the enzyme Streptococci isolate (H5) which is identified as Streptococcus mutans serotype C which was selected as the best producible isolate for GTF with a specific activity of 2.6 U/mg. It was found that GTF of the chosen isolate (H5) was produced during the middle stationary phase (18-35 hours) and its maximal productivity was reached at 22 hours. Purification of S. mutans serotype (C) H5 GTF were done by ammonium sulfate, ionexchange chromatography (DEAE-Sephacel column) and gel-filtration chromatography using Sepharose 6B column. The best percent saturation use for precipitating GTF by ammonium sulfate was 20-40% with specific activity 2.4 U/ml. Two purified GTF enzymes (GTF-I and GTF-II) were detected with specific activity 35.5 U/mg, 8.3 U/mg after 96.1 and 22.6 fold of purification, respectively with yield 17.2%. Determination of purified GTF (GTF-I, GTF-II) molecular weight was done by using gel-filtration chromatography (Sepharose 6B) column with presence of standard proteins. It was found that the molecular weights of GTF-I, GTF-II were 125819, 112201 Daltons, respectively.
