Revision as of 18:53, 11 December 2013

This pages lists all the Glycoside Hydrolase (GH) Family pages in CAZypedia that have been given Curator Approved status, as well as those that are currently under construction or unassigned (i.e. lacking a Responsible Curator and Author).

Background

Strictly speaking, the term 'glycoside hydrolase' or 'glycosidase' refers to enzymes that catalyze the hydrolytic cleavage of the glycosidic bond to give the carbohydrate hemiacetal. Additionally, it is found that sequence-based classification methods often group in enzymes that have non-hydrolytic activities into the same families as hydrolytic enzymes.

Seminal publications on GH classification: [1, 2, 3, 4, 5].

Key reviews on GH and related mechanisms (e.g. GH4 enzymes and GH31 lyases): [6, 7, 8].

Curator Approved

Approve icon-50px.png

These pages have been approved by the Responsible Curator as essentially complete. CAZypedia is a living document, so further improvement of these pages is still possible; please see the individual pages for more information.

There are currently 139 Curator approved Glycoside Hydrolase (GH) Family pages in CAZypedia.

Under construction

Under construction icon-blue-48px.png

These pages are currently under construction in CAZypedia. As such, the Responsible Curator has deemed that the page's content is not quite up to CAZypedia's standards for full public consumption. All information on these pages should therefore be considered to be under revision and may be subject to major changes.

There are currently 9 Glycoside Hydrolase Family pages under construction in CAZypedia.

Unassigned pages

The following Unassigned pages are currently lacking a Responsible Curator and one or more Authors. If you are an expert on any of these families and would like to help us improve CAZypedia by getting involved with the production and maintenance of the corresponding page(s), please contact a member of the Board of Curators directly, or via this form.

There are currently 41 Glycoside Hydrolase Family pages in CAZypedia that have not been assigned to a Responsible Curator.

Deleted families

The following families have been deleted from the CAZy database. Please see the individual CAZypedia pages and links to the corresponding CAZy DB pages for specific explanations.

There are currently 8 pages in CAZypedia that describe Glycoside Hydrolase families deleted from the CAZy DB.
