Cell type | FBP, nmole/ mg protein | Tetramer, % | Dimer, % |
---|---|---|---|
M/1 | 0.22 ± 0.04 | 63.5 ± 0.3 | 36.5 ± 0.6 |
Δ79-83 | 0.40 ± 0.10n.s. | 59.9 ± 1.6n.s. | 40.1 ± 1.6n.s. |
E7/2 | 0.40 ± 0.04 | 47.2 ± 0.9 | 52.8 ± 0.8 |
(P < 0.05) | (P < 0.001) | (P < 0.001) |
Control and E7-expressing NIH3T3 subclones were used for gel filtration analysis of M2-PK as indicated; the results are given as the relative amounts of the tetrameric and dimeric forms of M2-PK ( ± SEM, n = 4). FBP levels were determined in perchloric acid extracts. ± SEM, n = 5. n.s., not significant.
