IUPAC-IUB classification of acyl carrier protein (E. coli)?

[Beverly Seavey -Kung]

    Does anyone know: does E. coli acyl carrier protein have an enzyme
	classification # or is it considered to be a passive acceptor only?
	I can find things like ACP hydrolase and ACP-acetyl transferase
	but nothing for ACP itself. According to Wakil (Ann. Rev. Biochem 198?)
	in eukaryotes ACP is part of the fatty acid synthetase itself, but I
	can't find anything about this for the coli protein.
