Physiological activators of invertase from Hevea brasiliensis latex
Potassium or sodium nitrates or phosphates, and thiols such as reduced glutathione or cysteine, stimulate the activity of invertase from Hevea brasiliensis latex. These activators raise the V max but do not affect the K m of the enzyme for sucrose. The action of these effectors is additive. Their ef...

description | Potassium or sodium nitrates or phosphates, and thiols such as reduced glutathione or cysteine, stimulate the activity of invertase from
Hevea brasiliensis latex. These activators raise the V
max but do not affect the K
m
of the enzyme for sucrose. The action of these effectors is additive. Their efficiency is pH dependent, being higher below pH 7.0 and markedly decreasing above it. |
