The results show that all the hmgr genes from pigs, cattle and chickens are astable enzyme proteins with the same gene sequence characteristics and encoding protein and physical and chemical properties; all the amino acid sequences have a high degree of homology, containing two conservative HMG-CoA binding motifs and two NADPH binding motifs; all the amino acid sequences, containing signal peptide, are secreted proteins; they are all hydrophobic transmembrane proteins with five transmembrane domains; random coil and α-helix are the main structural elements in the HMGR polypeptide chain; all the predictions of three-dimensional structure are V- shaped; there are more closer evolution relationship between the HMGR gene from pigs and cattle.
