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]. [1]. 10997907.

4'-phosphopantetheinyl transferase superfamily protein

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.

phosphopantetheine--protein transferase domain

This HMM models a domain active in transferring the phophopantetheine prosthetic group to its attachment site on enzymes and carrier proteins. Many members of this family are small proteins that act on the acyl carrier protein involved in fatty acid biosynthesis. Some members are domains of larger proteins involved specialized pathways for the synthesis of unusual molecules including polyketides, atypical fatty acids, and antibiotics.

holo-ACP synthase

Formerly dpj. This enzyme adds the prosthetic group, phosphopantethiene, to the acyl carrier protein (ACP) apo-enzyme to generate the holo-enzyme. Related phosphopantethiene--protein transferases also exist. There is an orthologous domain in eukaryotic proteins.
