We have found 3 software records in our database eligible for .prproj to .mxf file format conversion.
The best and perhaps also only software that can reliably perform prproj to mxf conversion would be Adobe Premiere Pro. Not only are .prproj files projects from this software but it also supports MXF (Material Exchange format). Supposedly tools like Vegas Pro also can be used for this, but it's safe to assume that using the original software is best option.
