Doubtful, because that's a premium economy fare class on LH.
I'd guess it maps to M, H, or U, but that's just based on the fare structure, not any particular experience with the fare.
It would be helpful to have more information. As far as I can tell from a quick look at EF, UA does not typically sell E as an LH codeshare fare class.
