CAZypedia needs your help!
We have many unassigned pages in need of Authors and Responsible Curators. See a page that's out-of-date and just needs a touch-up? - You are also welcome to become a CAZypedian. Here's how.

This page lists all the Carbohydrate Esterase (CE) Family pages in CAZypedia that have been given Curator Approved status, as well as those that are currently under construction.
Overview
As described in the CAZy database CE familes page header:
"Carbohydrate esterases [also formally including carbohydrate amidases] catalyze the de-O or de-N-acylation of substituted saccharides. Since an ester = acid + alcohol, we consider two classes of substrates for carbohydrate esterases: those in which the sugar plays the role of the "acid", such as pectin methyl esters and those in which the sugar behaves as the alcohol, such as in acetylated xylan. A number of possible reaction mechanisms may be involved: the most common is a Ser-His-Asp catalytic triad catalyzed deacetylation analogous to the action of classical lipase and serine proteases but other mechanisms such as a Zn2+ catalyzed deacetylation prevails in some families."
The following reviews together provide a useful overview to this class of CAZymes: [1, 2].
Curator Approved
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 8 Curator approved Carbohydrate Esterase (CE) Family pages in CAZypedia.
Under construction
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 3 Carbohydrate Esterase 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. Undergraduate students, (post)graduate students, post-doctoral researchers, research associates, and professors are all welcomed to contribute!
There are currently 8 Carbohydrate Esterase 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 1 pages in CAZypedia that describe Carbohydrate Esterase families deleted from the CAZy DB.
