Abstract The variation of large and small subunits 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 correspond
