The Clan AA Reference Database (CAARD), is a database of ancestral maximum likelihood reconstructions (AMLRs), sequence logos and HMMs constructed based on different protein families according to estimations of their taxonomy and relationships. The objetive is to investigate the major consensus and phylogeny to classify the different protein families. For more details see, Llorens,C. Futami,R., Renaud,G and A. Moya (2009). Bioinformatic Flowchart and Database to Investigate the Origins and Diversity of Clan AA Peptidases. Biology Direct, 4:3 (https://link.springer.com/article/10.1186/1745-6150-4-3)
