Please try to use these secondary structure predictions:

Here is the sequence logo predicted by the SAM server.

H = helix
E = sheet
C = loop (or coil)

The taller the letter at each position, the higher the probability of that specific secondary structure for that amino acid.

For example, the amino acid Leucine at residue 26 is highly predicted to be part of a helix. However, the Leucine at residue 34 is predicted to have an equal probability of being anything.

The protein is Bile acid

The protein is Bile acid 7a-dehydratase

It belongs to the bacteria organism Eubacterium sp.

Catalyzes the dehydratation of 7-alpha,12-alpha-dihydroxy-3-oxochol-4-enoate. The enzyme can also use 7-alpha-hydroxy-3-oxochol-4-enoate as a substrate but not 7-alpha,12-alpha-dihydroxy-3-oxochol-5-beta-anoate, 3-alpha,7-alpha,12-alpha-trihydroxychol-5-beta-anoate or 7-beta-hydroxy-3-oxochol-4-enoate
