Abstract:
Bioinformatic methods were employed to analyze the amino acid sequences of Betaine Aldehyde Dehydrogenase (BADH) from Genbank database，such as Beta vulgaris, Spinacia oleracea, Atriplex hortensis, Suaeda liaotungensis, Zea mays，etc.The results showed that BADHs were stable proteins.Ala and Glu were abundant in those BADHs.Sequence alignment revealed that BADHs were highly homologous in different plants，and the residues involved with function were very conservative.BADHs had been found to be targeted to different subcellular compartments.BADHs could be used as genetic differentiation and an important basis for the study of molecular evolution.There was no signal peptide in segmental plants.BADHs had no transmembrane structure and could be phosphorylated by protein kinase.α-helix were the major structural element of polypeptide chain.Meanwhile,BADHs contained typical function domains of ALDH.This study provided a theoretical basis for both the enzymatic mechanism of BADHs and the plant resistance to environmental stress.
