Chains	Accession	Short Name	Description	Provenance Source (Version)
A, B, C	ARO:3004122	Klebsiella pneumoniae OmpK37	Klebsiella pneumoniae outer membrane porin protein. Is preferentially detected in porin-deficient strains. Functional characterization of this new porin revealed a narrower pore than those of porins OmpK35 and OmpK36, which did not allow penetration by certain beta-lactams. Also, when a resistant strain expresses porin OmpK37 is less susceptible to cefotaxime and cefoxitin than when it is expressing either OmpK36 or OmpK35.	CARD (4.0.1)
