Description of amino acid substitutions in de novo produced site-directed chlamydomonas D1 mutants.

The reported set of D1 mutations could account for the radiation tolerance previously found in D1 random mutants surviving neutron and proton exposure, and was selected to produce the corresponding site-directed mutants.aThe side chain polarity is presented according to [53], the hydropathy index is cited as in [54], the amino acids reactivity classes are reported in Table 2.
