[PyMOL] displaying protein with propeptide

[<an...@cb...>]

Hi,

I am having problems displaying proteins with unusual residue numbering,
such as proteins with propeptides. An example is 1cs8, which starts off =
like
this:

ATOM      1  N   SER A   1P    -32.762  23.978  22.929  0.00 34.26
N =20
ATOM      2  CA  SER A   1P    -32.360  24.645  21.660  0.00 34.08
C =20
ATOM      3  C   SER A   1P    -32.303  26.162  21.821  0.00 33.91
C =20
ATOM      4  O   SER A   1P    -32.838  26.712  22.786  0.00 33.82
O =20
ATOM      5  CB  SER A   1P    -33.338  24.274  20.541  0.00 34.28
C =20
ATOM      6  OG  SER A   1P    -34.684  24.406  20.971  0.00 34.36
O =20
.
.
.
And later on comes the sequence corresponding to the mature protein:

ATOM   1060  N   ALA A   1      11.470  66.852  16.148  1.00 22.69
N =20
ATOM   1061  CA  ALA A   1      11.282  65.561  15.491  1.00 20.80
C =20
ATOM   1062  C   ALA A   1      10.621  65.677  14.113  1.00 20.33
C =20
ATOM   1063  O   ALA A   1       9.920  66.649  13.835  1.00 18.43
O =20
ATOM   1064  CB  ALA A   1      10.451  64.636  16.393  1.00 19.50
C =20
Etc.=20

If I open 1cs8 with PyMol, I can see everything in the "lines", "sticks" =
and
"surface" representation, but in ribbon or cartoon mode only part of the
protein is shown. What do I have to do to show the whole sequence?

How do I select residues with a "P" appended to the residue number? If I =
say
"select resi 1P-5P" I get both 1P-5P and 1-5.=20

Any help will be appreciated! (I am using PyMol version 0.98 for =
Windows).
