    Protein Summary

    There are two highly homologous carboxylesterases in Bacillus subtilis 168. The CL4101A is CARBOXYLESTERASE NA which is 98% id from CARBOXYLESTERASE NP of Bacillus subtilis Thai I-8. The other YbfK is 64% identical to NP.  (Note: The sequence of NP in papers published by Quax's lab keeps changing, so maybe NP is actually the same as NA?).

    There is some literature in which NP is chemically characterized. It may be useful "Development of a new Bacillus carboxyl esterase for use in the resolution of chiral drugs". The structure itself isn't new fold, in fact, it is quite similar to many other enzymes in the pdb, mostly hydrolases. However, there are some differences around the active site, eg helix 207-220 of 1c4x is not present in CL4101A. The active site triad: S130-H274-D245. It is also interesting to see there are two conformers observed for the S130 (one is HB to H274, the other not).

    An N-terminal helix and a new dimerization mode are observed here for the first time within this fold.
