The carbohydrate-active enzyme database: functions and literature
Open accessAbstract
Thirty years have elapsed since the emergence of the classification of carbohydrate-active enzymes in sequence-based families that became the CAZy database over 20 years ago, freely available for browsing and download at www.cazy.org. In the era of large scale sequencing and high-throughput Biology, it is important to examine the position of this specialist database that is deeply rooted in human curation. The three primary tasks of the CAZy curators are (i) to maintain and update the family classification of this class of enzymes, (ii) to classify sequences newly released by GenBank and the Protein Data Bank and (iii) to capture and present functional information for each family. The CAZy website is updated once a month. Here we briefly summarize the increase in novel families and the annotations conducted during the last 8 years. We present several important changes that facilitate taxonomic navigation, and allow to download the entirety of the annotations. Most importantly we highlight the considerable amount of work that accompanies the analysis and report of biochemical data from the literature.

NEU1 is part of the GH33 family of glycoside hydrolases.
“NEU1 is part of the GH33 family of glycoside hydrolases (64), which comprises bacterial and eukaryotic enzymes (65–68) that release terminal sialic acids from glycans or transfer these sugar residues onto other glycans.”
From Structure of the immunoregulatory sialidase NEU1 (2023) · cites this paper as [64]
The Introduction’s “Maintenance of the modular classification and daily updates” section explains that GH denotes glycoside hydrolase families, but does not identify NEU1 or GH33. Searches for “NEU1 GH33” and “GH33 sialidase neuraminidase” found no passage in our copy establishing NEU1’s family assignment. (LLM, conf=0.76)

About these checks
Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.
Statistics and arithmetic are recomputed, not judged.
Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
