    Protein Summary

    The gene Ava_3312 from Anabaena variabilis encodes a putative XisH family protein PF08814, an FdxN element excision controlling factor protein.  The structure of the close homologue (86% sequence identity) from the Nostoc punctiforme has been solved 2INB.  The protein belongs to the class of alpha and beta (a+b) proteins and adopts a restriction endonuclease-like fold type SCOP52979.  XisH together with the XisF and XisI proteins are required for excision from the chromosome of the fdxN element, along with two other DNA elements, during heterocyst differentiation in cyanobacteria.
