A288F | significant loss of lycopaoctaene production when compared to wild-type. Increased residue size in the mutant blocks binding of geranylgeranyl diphosphate in the S1 pocket | Botryococcus braunii |
M180L | mutant retains the ability to produce lycopaoctaene | Botryococcus braunii |
additional information | mutating Ser276 and Ala288 residues to those found in human squalene synthase largely converts LOS from lycopaoctaene production to C30 squalene production | Botryococcus braunii |
S276Y | significant loss of lycopaoctaene production when compared to wild-type. Increased residue size in the mutant blocks binding of geranylgeranyl diphosphate in the S1 pocket | Botryococcus braunii |
S276Y/A288F | mutant shows a drastic reduction in the ability to produce lycopaoctaene and C35H58 compared to wild-type enzyme | Botryococcus braunii |
T65V | mutant retains the ability to produce lycopaoctaene | Botryococcus braunii |
T65V/A288F | when comparing the M7 double mutant to the parent A288F background, T65V/A288F does not show a difference in lycopaoctaene production, but C35H58 production is slightly increased and squalene formation is significantly reduced | Botryococcus braunii |
T65V/M180L | activity of the mutant enzyme is similar to that of the wild-type enzyme | Botryococcus braunii |
T65V/M180L/A288F | mutant shows activity similar to that of the M4 parent background | Botryococcus braunii |
T65V/M180L/S276Y A288F | in comparison to the M9 parent background, the mutant enzyme shows a further reduction in C35H58 production and no significant change in lycopaoctaene and squalene formation | Botryococcus braunii |
T65V/M180L/S276Y/A288F/V289C | in comparison to the M9 parent background, the mutant enzyme shows a further reduction in C35H58 production and no significant change in lycopaoctaene and squalene formation | Botryococcus braunii |
V289C | mutant retains the ability to produce lycopaoctaene | Botryococcus braunii |
V289C/S276Y | for the V289C/S276Y double mutant, in comparison to the S276Y parent background, a small increase in C35H58 production is observed, whereas the activities for lycopaoctaene and squalene production remain the same | Botryococcus braunii |
