Helical

... is composed of 146 amino acids (Perutz, 1978). Both alpha and beta globin proteins share similar secondary and tertiary structures, each with 8 helical segments (labeled helix A-G) (Keates, 2004). Each globin chain also contains one heme molecule." FZ you have a diagram of the heme molecule. ...

I hope somebody can help me out here. I understand that secondary walls are laid in xylem tissue in one of the following ways: annular thickenings, helical thickenings, scariform thickenings, reticulate thickenings. My questions are as follows: 1. Are these only present on primary xylem and there ...

... peptide fragment of a LamaG protein which is 11 aminoacids long. I want to ask, if it is possible to make tertiary structure prediction and alpha helical wheel blott with 11 aminoacids: GRWHKVSVRWE Can anyone help me with the data? I want to publisch some facts of this peptide fragment. THX! p.s. ...
