HEXA (Hexosaminidase A) is the functional enzyme and encoded by the HEXA gene. The main function of this enzyme is the hydroxylation of the gangliosides.
The mutation in this gene leads to the lysosomal storage disease. The GM2 starts accumulating in the lysosomes and causes Tay Sach's disease. This is a genetic disorder that leads to the breakdown of the cells of the spinal cord and the brain.
Archaean cell wall don't have peptidoglycan, yet they may have <em>, polysaccharides, glycoproteins, or protein-based cell dividers </em>
Bacterial cell walls are made of peptidoglycan (likewise called murein), which is produced using polysaccharide chains cross-connected by abnormal peptides containing D-amino acids
