    Protein Summary

    The lp_3665 gene from Lactobacillus plantarum encodes the NP_786857 protein, a putative phenolic acid decarboxylase (Pfam05870). Phenolic acids (ferulic, p-coumaric and caffeic acids) have protective role against oxidative damage diseases (coronary heart disease, stroke, and cancers) and are used in processed foods as a natural antioxidants. Vinyl phenol derivatives, created during decarboxylation of phenolic acids, were found to be much more inhibitory to the E. coli then these acids themself (PubMed:11229892).

    2gc9 structure has an up-and-down, ten stranded beta barrel fold. Most proteins with up-and-down beta barrel fold are integral transmembrane proteins. However, 2gc9 barrel has an elongated shape, which can be described as consisting of two sheets, while integral membrane beta barrel proteins are  much more symmetrical, almost round.

    A second protein from this family, ferulate decarboxylase from Bacillus subtilis, PDB code 2p8g was recently solved by JCSG.
