In Table I the results of this calculation are listed for all four classes of
targeting signals. Of 9368 Arabidopsis proteins sufficiently conserved
for phylogenetic analysis, 1700 were calculated to come from
cyanobacteria [b]. Their subcellular targeting was calculated by TargetP
(Table II, col. 2), and extrapolation to the entire genome (25 678 genes)
was then performed by multiplying by a factor of 2.74 (25 678/9368; col.
