endo glucosaminidase ?

[schaub at chclu.chemie.uni-konstanz.de]

Hello

I am searching a endo beta-N-Acetylglucosaminidase which would cleave a 
p-Nitophenylglycoside of a di- or trisaccharide with a terminal GlcNac.
Would endo F1 or PNGase F cleave this ?
Does anyone have experience with that type of cleavage ? and where you can
purchase the enzyme for this purpose. 


thank you in advance
