  A dynamical calculation of pentaquark systems with quark contents
$uudd\bar{s}$ is performed in the framework of quark delocalization color
screening model with the help of resonating group method. The effective
potentials between baryon and meson clusters are given, and the possible bound
states or resonances are investigated. The single calculations show that the
$NK^{*}$ with $I=0, J^{P}=\frac{1}{2}^{-}$, $\Delta K^{*}$ with $I=1,
J^{P}=\frac{1}{2}^{-}$, and $\Delta K^{*}$ with $I=2, J^{P}=\frac{3}{2}^{-}$
are all bound, but they all turns into scattering states by coupling with the
corresponding open channels. A possible resonance state $\Delta K^{*}$ with
$I=1, J^{P}=\frac{5}{2}^{-}$ is proposed. The mass is around $2110.5$ MeV, and
the decay modes are $NK$ in $D$-wave or $NK\pi\pi$ in $P$-waves.
