Does Pfam agree with the content of the Wikipedia entry ?
Pfam has chosen to link families to Wikipedia articles. In some case we have created or edited these articles but in many other cases we have not made any direct contribution to the content of the article. The Wikipedia community does monitor edits to try to ensure that (a) the quality of article annotation increases, and (b) vandalism is very quickly dealt with. However, we would like to emphasise that Pfam does not curate the Wikipedia entries and we cannot guarantee the accuracy of the information on the Wikipedia page.
Editing Wikipedia articles
Before you edit for the first time
Wikipedia is a free, online encyclopedia. Although anyone can edit or contribute to an article, Wikipedia has some strong editing guidelines and policies, which promote the Wikipedia standard of style and etiquette. Your edits and contributions are more likely to be accepted (and remain) if they are in accordance with this policy.

How your contribution will be recorded
Anyone can edit a Wikipedia entry. You can do this either as a new user or you can register with Wikipedia and log on. When you click on the "Edit Wikipedia article" button, your browser will direct you to the edit page for this entry in Wikipedia. If you are a registered user and currently logged in, your changes will be recorded under your Wikipedia user name. However, if you are not a registered user or are not logged on, your changes will be logged under your computer's IP address. This has two main implications. Firstly, as a registered Wikipedia user your edits are more likely seen as valuable contribution (although all edits are open to community scrutiny regardless). Secondly, if you edit under an IP address you may be sharing this IP address with other users. If your IP address has previously been blocked (due to being flagged as a source of 'vandalism') your edits will also be blocked. You can find more information on this and creating a user account at Wikipedia.

The community annotation is a new facility of the Pfam web site. If you have problems editing or experience problems with these pages please contact us.

|Glycoside hydrolases related to GH101 family|
Glycoside hydrolases EC 3.2.1. are a widespread group of enzymes that hydrolyse the glycosidic bond between two or more carbohydrates, or between a carbohydrate and a non-carbohydrate moiety. A classification system for glycoside hydrolases, based on sequence similarity, has led to the definition of >100 different families. This classification is available on the CAZy (http://www.cazy.org) web site, and also discussed at CAZypedia, an online encyclopedia of carbohydrate active enzymes.

Glycosyl hydrolases related to GH101 family, GHL1-GHL3 Provide feedback
This family of bacterial and lower eukaryote glycosyl hydrolases is related to CAZy family GH101, and is made up of sub-families GHL1-GHL3. In the example C02A26 the substrate-binding Asp is residue 596, the nucleophilic Asp is residue 706, and the proton donor Glu is residue 747.

This large superfamily contains a range of glycosyl hydrolase enzymes that possess a TIM barrel fold. This CLAN merges clans GH-A, GH-D, GH-H and GH-K from CAZy.
The clan contains the following 50 members:Alpha-amylase Alpha_L_fucos Cellulase Cellulase-like DUF187 DUF4015 DUF4038 DUF4434 GHL1-3 GHL12 GHL13 GHL15 GHL5 GHL6 Glyco_hydr_30_2 Glyco_hydro_1 Glyco_hydro_10 Glyco_hydro_101 Glyco_hydro_114 Glyco_hydro_14 Glyco_hydro_17 Glyco_hydro_18 Glyco_hydro_20 Glyco_hydro_25 Glyco_hydro_26 Glyco_hydro_2_C Glyco_hydro_3 Glyco_hydro_30 Glyco_hydro_31 Glyco_hydro_35 Glyco_hydro_39 Glyco_hydro_42 Glyco_hydro_44 Glyco_hydro_53 Glyco_hydro_56 Glyco_hydro_59 Glyco_hydro_66 Glyco_hydro_70 Glyco_hydro_72 Glyco_hydro_77 Glyco_hydro_79n Glyco_hydro_97 Glyco_hydro_cc hDGE_amylase Lipid_bd Melibiase NAGidase NAGLU Raffinose_syn Xylanase
We make a range of alignments for each Pfam-A family:
- the curated alignment from which the HMM for the family is built
- the alignment generated by searching the sequence database using the HMM
- Representative Proteomes (RPs) at 15%, 35%, 55% and 75% co-membership thresholds
- alignment generated by searching the NCBI sequence database using the family HMM
- alignment generated by searching the metagenomics sequence database using the family HMM
You can see the alignments as HTML or in three different sequence viewers:
- Pfam viewer
- an HTML-based viewer that uses DAS to retrieve alignment fragments on request
