Intestinalin (P30), a 30 aa peptide derived from the first 30 aas of LysC, derived from Clostridium intestinale strain URNW. The GenBank accession # given with this entry corresponds to the entire LysC protein as the 30 aa peptide does not yet have an accession #. The protein is predicted by the WHAT program to have an N-terminal TMS although this region does not show strong hydrophobicity. It forms large pores due to oligomerization of the 30 aa peptide.
