标题Re: [生医] [生化]-台大98-一般生化 帮忙核对
时间Mon Feb 15 00:04:22 2010
想藉这个标题请教一题
20.A singal sequence has to be expected in the precursors of all the following
proteins except
A.ribosomal proteins
B.the sodium-potassium ATPase in the plasma membrane
C.collagen in the extracellular matrix of connective tissue
D.signal peptidase
E.acid maltase, a lysomal hrdrolase
这题我是选A 印象中singal sequence似乎是可以把合成出来的蛋白带去他该去的地方...
有人知道这一题该选谁吗??
40.Interferon activated enzyme
A.phosphatase
B.phosphorylase
C.phosphodiesterase
D.Janus kinase
E.Akt/PKB
这一题我就不知道要怎麽选了= =
请高手帮帮忙~谢谢

8F：→ teamophoenix:说错了，猜D，其实这是wikipedia说的，不知道对不对 02/15 20:07
9F：推 TreeMan:ribosomal protein在cytosol合成後会被送到nuclear，会需 02/16 22:17
10F：→ TreeMan:要NLS，也是siganl sequence的一种，所以应该也有，这题我 02/16 22:17
11F：→ TreeMan:选signal peptidase，因为它是在ER处作用，非一般具signal 02/16 22:18
