PF178374'-phosphopantetheinyl transferase N-terminal domain (4PPT_N)4'-phosphopantetheinyl transferase N-terminal domainThis entry represents the N-terminal domain from 4'- phosphopantetheinyl transferase enzymes. This domain is structurally related to the Pfam:PF01648 domain with which it forms a pseudodimeric arrangement [2]. Domain

This post-translational modification renders holo-ACP capable of acyl group activation via thioesterification of the cysteamine thiol of 4'-PP [1]. This superfamily consists of two subtypes: The ACPS type such as Swiss:P24224 and the Sfp type such as Swiss:P39135. The structure of the Sfp type is known [3], which shows the active site accommodates a magnesium ion. The most highly conserved regions of the alignment are involved in binding the magnesium ion.
