comparison of protein sequences shows the 57-kda subunit from arabidopsis to be nearly identical with the corresponding subunit in neurospora vacuolar membrane h+-atpase , very similar to the beta subunit of the archaebacterium sulfolobus , and slightly , but nevertheless significantly , homologous to the alpha and beta subunits of the f0f1-atpases .
