  As a consequence of having a positive partial transpose, bound entangled
states lack many of the properties otherwise associated with entanglement. It
is therefore interesting to identify properties that distinguish bound
entangled states from separable states. In this paper, it is shown that some
bound entangled states violate a non-symmetric class of local uncertainty
relations (quant-ph/0212090). This result indicates that the asymmetry of
non-classical correlations may be a characteristic feature of bound
entanglement.
