For CAZymes functions, glycoside hydrolases (GH) 57, GH1, and glycosyltransferases (GT) 75 families such as β-glucosidase, α-amylase, and self-glucosylating β-glucosyltransferase were enhanced in control group, while auxiliary activities (AA) 10, carbohydrate-binding modules (CBM) 73, GT28, and GT1 families such as copper-dependent lytic polysaccharide monooxygenases, chitin-associated modules of residues, 1,2-diacylglycerol 3-β-galactosyltransferase, and glucuronosyltransferase were elevated in CHD group. This evidence concerns the gene GH1 and coronary artery disorder.
