What's the largest prot. structure known?

Dear Xtallographers

  I am a layman who just loves to see those beautiful structures they show
in full color in Nature and Science.  Last year I was fortunate enough to
get to attend some lectures of men with names in the protein structure
community.  If I remember correctly one of them (Alwin Jones I think) said
that the lagrest structure determined to a reasonable (>3a) resolution was
somewhre close to 60 KDa.  Now I have three questions for you:

1) Does my memory serve me right?  (Given the fact that those guys would
not have said anything that wasn't true)
2) What is the current record (the largest single peptide that has had its
diffraction pattern traced)?
3) What is the current record for NMR? 

  I am sure there is someone in x-ray land who knows this, or at least has
the resources to extract this information from Brookhaven, PIR or wherever.
