which restriction sites are used ?

	Dear developers,

I am using EMBOSS version 2.4.1. I noticed the following : ApeKI is a 
restriction enzyme without commercial provider. If I do "redata ApeKI" I get :
------------
ApeKI

Recognition site is GCWGC leaving sticky ends
  Cut positions 5':0 3':0 [5':0 3':0]
Organism: Aeropyrum pernix K1
Methylated: ?(5)
Source: ATCC 700893

Isoschizomers:
   TseI        AceI        Taq52I      TseBI

----------------
So, it is there and has a cut site that should match GCAGC.
Yet, when I run remap or restrict with parameters -nocommercial -nolimit on a 
sequence containg GCAGC the restriction site is not found. Asking explicitly to 
look for enzyme ApeKI does not help, the enzyme is not even mentioned as "enzyme 
that does not cut".

Is that normal ?
