  We report on the first XMM-Newton observation of the bright Narrow-Line
Seyfert 1 galaxy Mrk 110. We find a narrow Fe K fluorescent line, a broad
component FWHM ~ 16500 km/s of the OVII triplet, either due to infall motions
or gravitational redshift effects in the vicinity of the central black hole, a
Comptonized accretion disc layer, and a strong starburst component. If the
broad redshifted soft X-ray components are due to gravitational redshift
effects, the distance of the line emitting regions ranges between about 0.2 and
1 light day with respect to the central black hole.
