    Protein Summary

    Gene Npun_R6570 from Nostoc punctiforme PCC 73102 encodes the YP_001869771 amino acid sequence (obsolete entry: ZP_00108720), a pyridoxamine 5'-phosphate oxidase-related, FMN-binding protein with significant similarity to proteins from COG3871.

    2i02 has significant structural similarity to proteins with structures classified as SCOP family: PNP-oxidase like [50476].

    Phylogenetic cooccurrence indicates that ZP_00108720 functions may be interdependent with the following proteins:
    ALR3356 [Q8YRT7], ALL4050 [Q8YPZ0], ALL4894 [Q8YMN9], ALL5264 [Q8YLN4], ALL3797 [Q8YQM3], BPHB [PHYB_ANASP] - Cyanobacterial phytochrome B (EC 2.7.3.-), ALR1320 [Q8YX95], ALL4647 [Q8YNC0], ALR0895 [Q8YYF5], and ALL3820 [Q8YQK3].
    Analysis of the crystallographic packing of 2i02 using the PQS server {Henrick, 1998 #73} indicates that a tetramer is the biologically relevant form.
