Abstract
The 69-12Q mutant of Chlamydomonas reinhardtti lacks ribulose-1,5-bisphosphate carboxylase activity, but retains holoenzyme protein. It results from a mutation in the chloroplast large-subunit gene that causes as isoleucine-for-threonine substitution at amino-acid residue 173. Considering that lysine-175 is involed in catalysis, it appears that mutations cluster at the active site.Keywords
