15473697-5	2004	Although the overall structural topology between BACE1 and BACE2 protease domains is quite similar, the former contains 3 disulfide bonds but the latter only two.	Disulfides	122-131	beta-secretase 2	Homo sapiens	59-64	
10965118-5	2000	In addition, and similarly to BACE, BACE2 differs from the other members of the human aspartic protease family in the number and distribution of putative disulfide bonds and in the presence of an extended C-terminal region which contains a predicted transmembrane segment.	Disulfides	154-163	beta-secretase 2	Homo sapiens	36-41
