Shirley Lee, a student in department of Life Sciences, was
bitten by a snake in the backyard of life science building.
She was so angry! Thus, she killed the snake and purified
several toxins from its venoms. She sequenced one of the
toxin, got this sequence:
1 L K C N K L V P L F Y K T C P A G K N I C Y K M F M V A T P
31 K L P V K R G C I D V C P K S S L L V R Y V C C N T D K C N
(1) Is this a new toxin? Please help him to identify this toxin.
ANSWER:this is not a new toxin.
(2) Can you find proteins that share sequence homology with
this toxin? Show them in multiple alignment form.
(3) Please predict its secondary structure.
(4) Please show its charge distribution.
