Structural basis for nicotinamide cleavage and ADP-ribose transfer by NAD+-dependent Sir2 histone/protein deacetylases

Template:ABSTRACT PUBMED 15150415

Function

[HST2_YEAST] NAD-dependent histone deacetylase that is involved in nuclear silencing events. Derepresses subtelomeric silencing and increases repression in nucleolar (rDNA) silencing. Its function is negatively regulated by active nuclear export.[1] [2] [3] [4] [5]

About this Structure

1szc is a 2 chain structure with sequence from Saccharomyces cerevisiae. Full crystallographic information is available from OCA.
