淀粉酶的化学结构式

这可是一种蛋白质啊，蛋白质具有四级结构，想写出酶的结构简式应该不是人类手工完成的事情。
还是给你些相关材料吧：

TMpred output for amy [ISREC-Server] Date: Sun May 21 1:44:34 Europe/Zurich 2006
Sequence: MHAWRR, length: 475
Prediction parameters: TM-helix length between 17 and 33
1) Possible transmembrane helices The sequence positions in brackets denominate the core region
Only scores above 500 are considered significant
Inside to outside helices : 4 found
from to score center
16 ( 16) 34 ( 34) 1388 25
155 ( 155) 178 ( 173) 387 165
242 ( 245) 266 ( 264) 187 255
437 ( 437) 459 ( 459) 549 447
Outside to inside helices : 2 found
from to score center
16 ( 16) 35 ( 33) 1017 25
438 ( 444) 466 ( 463) 390 455
2) Table of correspondences Here is shown, which of the inside->outside helices correspond to which of the outside->inside helices
Helices shown in brackets are considered insignificant
A "+"-symbol indicates a preference of this orientation
A "++"-symbol indicates a strong preference of this orientation
inside->outside | outside->inside
16- 34 (19) 1388 ++ | 16- 35 (20) 1017
( 155- 178 (24) 387 ++ ) |
( 242- 266 (25) 187 ++ ) |
437- 459 (23) 549 + |( 438- 466 (29) 390 )
3) Suggested models for transmembrane topologyThese suggestions are purely speculative and should be used with extreme caution since they are based on the assumption that all transmembrane helices have been found
In most cases, the Correspondence Table shown above or the prediction plot that is also created should be used for the topology assignment of unknown proteins
2 possible models considered, only significant TM-segments used
the models differ in the number of TM-helices !
-----> STRONGLY prefered model: N-terminus outside
2 strong transmembrane helices, total score : 1566
# from to length score orientation
1 16 35 (20) 1017 o-i
2 437 459 (23) 549 i-o
------> alternative model
1 strong transmembrane helices, total score : 1388
# from to length score orientation
1 16 34 (19) 1388 i-o
