GlycoEnzDB
Comprehensive glycoEnzyme database and dynamic pathway generation

Description: The GlycoEnzDB is a manually curated glycoEnzyme database, primarily focused on humans. It covers 390 enzymes across 28 pathway maps. Facilities are also available to create custom glycosylation reaction pathways using experimental data in SBML format and for pathway simulation

About

• Beta galactoisdase 1 removes terminal galactose residues from various contexts (glycolipids, glycoproteins, glycosaminoglycans)
• Alternative splicing of GLB1 creates an elastin binding protein important for maintaining cellular matrix integrity and lysosomal protein complex structure.
• G(M1) gangliosidosis disorder is caused by the lack of GLB1 activity.
• GLB1 forms complexes with other proteins in the lysosome, such as protective protein calthepsin A (PPCA), neuramidase 1 (NEU1), and GalNAc 6 sulfatase (GALNS).
