Substrate specificities
Glycoside hydrolases of family 7 cleave β-1,4 glycosidic bonds in cellulose. Several members also show activity on xylan. The substrate specificities found in GH7 are: endo-1,4-β-glucanase (EC 3.2.1.4); [reducing end-acting] cellobiohydrolase (EC 3.2.1.-) and chitosanase (EC 3.2.1.132).
This is an example of how to make references to a journal article [1]. (See the References section below). Multiple references can go in the same place like this [1, 2]. You can even cite books using just the ISBN [3]. References that are not in PubMed can be typed in by hand [4].
