  We consider the photo-excitation of charm and bottom pentaquarks with the
holographic assignments $[\frac 12\frac 12^-]_{S=0,1}$ and $[\frac 12\frac
32^-]_{S=1}$, in the photo-production of heavy vector mesons such as charmonia
and bottomonia near threshold. We use a Witten diagram to combine the s-channel
photo-excitation of holographic pentaquarks with a massive t-channel graviton
or tensor glueball exchange, to extract the scattering amplitude for heavy
meson photo-production in the threshold region. The pentaquark signal is too
weak to be detected at current electron facilities.
