Representation (unscaled) of the primary domain structure of the CDCP proteins in Arabidopsis thaliana and Oryza sativa. All the CDCPs were classified into two groups; single CBS domain containing proteins and two CBS domain containing proteins. Single CBS domain containing proteins were further classified into seven subgroups based on the additional domain(s) present in their sequences. Proteins containing only single CBS domain and no other functional domain were named as CBSX. Other proteins containing single CBS domain were named according to the presence of other functional domain. Two CBS domain containing proteins were classified into two subgroups. Proteins containing only two CBS domains and no other functional domain were named as CBSCBS and proteins containing two CBS domains and one PB1 domain were named as CBSCBSPB. The subfamily CBSIMPDH was observed only in O. sativa.
