Renaming Fasta ID's according to their number and on specific string length

Question

[Jiri]

Hi all,

I have a question about renaming my sequences in fasta format. I have 36,008 nucl. sequences and I need (want) rename them according to the following form. For every sequence, after > mark should follow string E_nip_trans_ (for all sequences) and after this I want place only digit string with length five, growing by one (from 00001 to 36008). But I don't have any idea how to do it.

>E_nip_trans_00001
>E_nip_trans_00002
>E_nip_trans_00003
> ...
>E_nip_trans_00010
> 
> ...
>E_nip_trans_00111  
> 
> ...
>E_nip_trans_36008

Thank you for reply!
