... similarity of PSRP-4 to PSRP-5 and PSRP-6. (A) Alignment of the transit peptide sequences of pre-PSRP-4 and six other similar precursors. It is followed by the alignment of themature proteins and Thx. ... cytosolicprecursors of PSRP-2, PSRP-3, and PSRP-4 have averagetargeting peptides (62, 58, and 54 residues long), and themature proteins are of 196, 121, and 47 residues length(molar masses, 21.7, 13.8 and ... °C for amplifications of 3¢-portions of Psrp-2 (P2-1/PR) and Psrp-3 (P3-1/PR), and 50–57 °C for amplification of 3¢-portion of Psrp-4 (P4-1/PR). Here, for example, P2-1/PR stands for PCR amplified...
