Branching enzyme

The branching enzyme enables the alpha 1,4 glycosidic linkages in
amylopectin.  This enzyme is also called the Q enzyme. 

Does anyone know what Q refers to?  I think it may be from the German.

Also, the de-branching enzyme that hydrolyses the alpha 1,6 linkages that
are built into amylopectin is sometimes referred to as the R enzyme.  What
does the R refer to?
