 Domain of unknown function (DUF4417) 
"This family of proteins is functionally uncharacterised. This family of proteins is found in bacteria and viruses. Proteins in this family are typically between 220 and 340 amino acids in length. There is a single completely conserved residue G (glycine) that may be functionally important".

 Pfam 
 Is a database of protein families (a protein family is a group of evolutionarily-related proteins, and is often nearly synonymous with gene family) that includes their annotations and multiple sequence alignments generated using hidden Markov models.


misc_feature Aa sequence:

Aa sequence (270 Aa):

-No helix-turn-helix nucleic acid binding motifs
 
-No prediction of transmembrane segments in protein 

- one PEST motif as potential proteolytic cleavage site 

- one site of cleavage between a signal sequence and the "mature exported protein"

  hypothetical "sequence" after cuttings

Is there a relationship with gp69 ?

"PD-(D/E)XK nucleases comprise a large and extremely diverse group of proteins that are involved in various processes of nucleic acid metabolism. Typically, different PD-(D/E)XK families share little or no recognizable sequence similarity except for the conserved signature of the active site. As it happens, the name of this large group of nucleases derives from the highly conserved ‘PD’ (in many cases only ‘D’) and ‘(D/E)XK’ (‘X’ denotes the non-conserved position) active site motifs".

My contribution:
in practice I verify if there is the Catalytic motif (P)D...Xn...(D/E)XK (where X is any aminoacid) in the sequences.

by Artemis software I download the  Fasta sequence of gp1 CDS and by Jemboss software  I analyse the Aa sequence:

!!!!!!!there are two catalytic motifs.

In the same way for gp69

!!!!!!!there are two catalytic motifs.

gp1 and gp69 have two Catalytic motif (P)D...Xn...(D/E)XK. One catalytic motif :   DX12(DXK)   in the sequences is in the same lenght.

Deduction:
gp1 could be a protein with the same activity of  the protein gp69.
