Question about disqualified person to IRA

[Ari Newman]

My 401K invested in a PPM a few months ago.  It owns a small percentage (6%) of an entity that owns a commercial property.  I'm not sure what percentage of ownership the GPs have but it's less than 50%.  

The GPs have started funding on another project in which I'd like to participate. I'm under the assumption that my other IRAs cannot invest in this project because the GPs are now disqualified to me personally or to my other IRAs. Is that correct or is it based on their percentage of ownership in the entity? So the other question is...can my Wife's IRA invest in the new project or are the GPs also disqualified to her IRA as she is my spouse?

thanks for your thoughts and feedback.
