  1. Protein families are uniquely identified by arbitrary group numbers, whose member proteins’ accession numbers are given in Additional file 1. For notes numbered *2 to *4, see Table 3. *1 In this category, only the largest five groups are shown. All proteins within these five groups were putative and uncharacterised, probable protein function was obtained by finding homologs on UniProtKB with >50 % sequence identity. For group three, although no homologs were found with >50 % sequence identity, it is possible that they are tetratricopeptide proteins as all within this group showed >30 % sequence identity to various tetratricopeptide proteins
