In case of inverting glycosyltransferase, when I use D-alpha-sugar as donor substrate than the sugar conjugation to substrate is in beta-configuration but when I use L-alpha-sugar as donor than I still get the alpha-configured glycoconjugate?
For example, while using UDP-D-alpha-glucose than the product will be beta-configured glycoconjugate but when I use dTDP-L-alpha-rhamnose than the product I get was alpha-configured glycoconjugate.
In this case if the enzyme is inverting than I should have beta-glycoconjugate as product. Can some body help me to solve this problem?
I am expecting answers with references.
Thank you respected Hans for clearing my doubt regarding the sugar conjugation and steriochemistry. Previously I thought the deoxy sugar dTDP-L-rhamnose is in alpha configured but now I found it is beta-configured naturally.
Thank you once again for your answer with references.
