Perhaps your data is more complex than first thought. You listed the following:

$uniprot
Q801F8  Q90XZ5; Q90XZ8;Name=dmrt1 
B7ZS42  A4PBN7; B7ZS44;Name=dmrt1-b ;PF00751;PF12374
Q157S1 Name=Crtc1  Synonyms=Mect1, 
$activ:

B7ZS42 | PF00751.13 PF12374.3 PF12374.3
Q157S1 | PF12886.2 PF12885.2 PF12884.2

Give the above listing, are you (potentially) expecting the following (keys/values)?

Q801F8 -> PF00751 PF12374 PF12374
B7ZS42 -> PF00751 PF12374 PF12374
Q157S1 -> PF12886 PF12885 PF12884

...

Q801F8 -> dmrt1 PF00751 PF12374 PF12374
Q90XZ5 -> dmrt1 PF00751 PF12374 PF12374
Q90XZ8 -> dmrt1 PF00751 PF12374 PF12374
B7ZS42 -> dmrt1-b PF00751 PF12374 PF12374
A4PBN7 -> dmrt1-b PF00751 PF12374 PF12374

It looks like there are multiple keys on a single $uniprot line:

Q801F8  Q90XZ5; Q90XZ8;Name=dmrt1
^^^^^^  ^^^^^^  ^^^^^^
   |       |       |
   +-------+-------+--- keys to be captured?

If this is the case, the current regex operating on the $uniprot lines would fail.

Let me know if the script needs to capture potentially multiple keys on a single $uniprot line...
