What happened to the Complex II page on the Ed Berry site at LBNL (

The site at LBNL is probably down for good now, but the pages are being moved to a new site with the help of digitalocean and noip:
The complex III (cyt bc1) site is also there:
and the old Berkeley Berry Group page:

Question about signal cleavage site of SDHA flavoprotein:

N-term sequencing of bovine FP gave SAKVSDA :
Birch-Machin, M. A., Farnsworth, L., Ackrell, B. A., Cochran, B., Jackson, S.,Bindoff, L. A., Aitken, A., Diamond, A. G. & Turnbull, D. M. (1992). The sequence of the flavoprotein subunit of bovine heart succinate dehydrogenase.
J Biol Chem 267, 11553-8.

However for the porcine FP the N-term sequence is SSAKV:
Huo, X., Su, D., Wang, A., Zhai, Y., Xu, J., Li, X., Bartlam, M., Sun, F.
& Rao, Z. (2007). Preliminary molecular characterization and crystallization of mitochondrial respiratory complex II from porcine heart. Febs J 274, 1524-9.

(The latter cutting point was confirmed for human FP by mass spec,
but I don't remember the reference.)
