of RuBPcase from temperature-sensitive mutant of Anjibaicha (Camellia sinensis) during its stage albescent process was investigated as well as the changes of the enzyme activities. The relationship between the levels of the RuBPcase subunits and the activities of proteinase was also discussed. It was found the levels of both large and small subunits were low at the albescent stage and became normal after leaves recovered to green, which corresponded with the enzyme activity change. Meanwhile, the high activity of protease and the lowering of leaf soluble protein content. At the albescent stage were the direct reasons for the accumulation of free amino acids.Key words　Anjibaicha；Stage albescent mutation；Temperature sensitive mutant；Proteinase； RuBPcase
