A, B, C, D	PF17837	4'-phosphopantetheinyl transferase N-terminal domain (4PPT_N)	4'-phosphopantetheinyl transferase N-terminal domain	This 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
A, B, C, D	PF01648	4'-phosphopantetheinyl transferase superfamily (ACPS)	4'-phosphopantetheinyl transferase superfamily	Members of this family transfers the 4'-phosphopantetheine (4'-PP) moiety from coenzyme A (CoA) to the invariant serine of Pfam:PF00550.

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 prosthetic group acts as a a 'swinging arm' for the attachment of activated fatty acid and amino-acid groups. This domain forms a four helix bundle. This family includes memb ...	A 4'-phosphopantetheine prosthetic group is attached through a serine. This prosthetic group acts as a a 'swinging arm' for the attachment of activated fatty acid and amino-acid groups. This domain forms a four helix bundle. This family includes members not included in Prosite. The inclusion of these members is supported by sequence analysis and functional evidence. The related domain of Swiss:P19828 has the attachment serine replaced by an alanine.	Domain
