Table 1 Overview of inventory of SRP in protozoa and fungi. SRP RNAs and proteins were predicted as described in the text. Symbols are as follows: +) subunit found, -) subunit not found and genome complete, *) previously reported subunit, M) multiple SRP RNA-like sequences were found and P) only partial RNA sequence found. Empty cells are instances where subunit has not been found and where there is no complete genome assembly and preliminary gene annotation.
