additional information
-
both the free and immobilized dextransucrase work best with 0.2 mM CaCl2 and exhibit 6062 and 5830 U/mg specific activity, respectively
Ca2+
-
increases the enzyme activity in the fermentation culture 2fold at 0.005% CaCl2, and increases the enzyme stability to up to 120 days
Ca2+
1 mM, enhances the transferase activity by 116%
-
1 mM, stimulates activity of enzyme N, enzyme I is inhibited
Mn2+
-
inhibits hydrolysis activity almost entirely, but activates transferase activity at 1 mM
-
inhibits hydrolysis activity but has no effect on transferase activity which constitutes to more than 90% of the overall activity, Zn2+ has therefore no influence on overall activity. Al3+ and Mg2+ also have no significant influence on activity
additional information
-
2 enzyme forms: I and N, enzyme I is gradually converted into enzyme N upon ageing, conversion is stimulated in the presence of NaCl
additional information
-
DSRBCB4 activity is not affected by Mg2+, K+, or Na+
additional information
-
the enzyme is not or poorly affected by Ca2+, K+, and pepstatin
additional information
-
Mn2+ has no influence on hydrolysis and transferase activity. Al3+ and Na+ also do not significantly influence overall activity
additional information
poor effects by Zn2+, Mg2+, and Ni2+ at 1-2 mM
