Members of this family transfers the 4'-phosphopantetheine (4'-PP) moiety from coenzyme A (CoA) to the invariant serine of Pfam:PF00550. 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.
This domain is found at the N-terminal end of human 4'-phosphopantetheinyl transferase (also known as L-aminoadipate -semialdehyde dehydrogenase-phosphopantetheinyl transferase, AASDHPPT), which catalyses the post-translational modification of target ...
This domain is found at the N-terminal end of human 4'-phosphopantetheinyl transferase (also known as L-aminoadipate -semialdehyde dehydrogenase-phosphopantetheinyl transferase, AASDHPPT), which catalyses the post-translational modification of target proteins by phosphopantetheine. This protein consists of two nearly identical domains (this entry and Pfam:PF01648) connected by a short linker region. Both domains show a pair of beta-sheets connected by a loop region [2].
