Mechanism of luciferase degradation?

[Bernard P. Murray, PhD]

Hello all,
     The subject line pretty much sums up the question - How is
firefly luciferase degraded?  Lysosomes?  Proteasome?  Ubiquitination?
I am primarily interested in the pathway(s) used during expression
in S.cerevisiae but any answer should prove helpful.  I didn't see
anything appropriate using Medline.

     Okay, while I am about it, is anything known about the
degradation of other common reporters? - CAT, beta-gal,
unfused GFP etc.

     Thanks for any hints,
          Bernard
