Accepted name: holo-[acyl-carrier-protein] synthase
Reaction: CoA-[4'-phosphopantetheine] + an apo-[acyl-carrier protein] = adenosine 3',5'-bisphosphate + an [acyl-carrier protein]
Glossary: apo-[acyl-carrier protein] = a family of proteins or protein domains that contain a conserved serine residue, which are involved in acyl-group transfer.
[acyl-carrier protein] = holo-[acyl-carrier protein] = ACP = holo-ACP = the active form of apo-[acyl-carrier protein], in which the hydroxyl group of the conserved serine is substituted by a 4'-phosphopantetheine group, resulting in a sulfydryl group at which the acyl group to be transferred may then be substituted.
Other name(s): acyl carrier protein holoprotein (holo-ACP) synthetase; holo-ACP synthetase; coenzyme A:fatty acid synthetase apoenzyme 4'-phosphopantetheine transferase; holosynthase; acyl carrier protein synthetase; holo-ACP synthase; PPTase; AcpS; ACPS; acyl carrier protein synthase; P-pant transferase; CoA:apo-[acyl-carrier-protein] pantetheinephosphotransferase; CoA-[4'-phosphopantetheine]:apo-[acyl-carrier-protein] 4'-pantetheinephosphotransferase
Systematic name: CoA-[4'-phosphopantetheine]:apo-[acyl-carrier protein] 4'-pantetheinephosphotransferase
Comments: Requires Mg2+. All polyketide synthases, fatty-acid synthases and non-ribosomal peptide synthases require post-translational modification of their constituent acyl-carrier-protein (ACP) domains to become catalytically active. The inactive apo-proteins are converted into their active holo-forms by transfer of the 4'-phosphopantetheinyl moiety of CoA to the sidechain hydroxy group of a conserved serine residue in each ACP domain [3]. The enzyme from human can activate both the ACP domain of the human cytosolic multifunctional fatty-acid synthase system (EC 2.3.1.85) and that associated with human mitochondria as well as peptidyl-carrier and acyl-carrier-proteins from prokaryotes [6]. Removal of the 4-phosphopantetheinyl moiety from holo-ACP is carried out by EC 3.1.4.14, [acyl-carrier-protein] phosphodiesterase.

Other name(s): CobS; cobalamin synthase; cobalamin-5'-phosphate synthase; cobalamin (5'-phosphate) synthase
Systematic name: adenosylcobinamide-GDP:α-ribazole ribazoletransferase
Comments: In Salmonella typhimurium LT2, under anaerobic conditions, CobU (EC 2.7.7.62 and EC 2.7.1.156), CobT (EC 2.4.2.21), CobC (EC 3.1.3.73) and CobS (EC 2.7.8.26) catalyse reactions in the nucleotide loop assembly pathway, which convert adenosylcobinamide (AdoCbi) into adenosylcobalamin (AdoCbl). CobT and CobC are involved in 5,6-dimethylbenzimidazole activation whereby 5,6-dimethylbenzimidazole is converted to its riboside, α-ribazole. The second branch of the nuclotide loop assembly pathway is the cobinamide activation branch where AdoCbi or adenosylcobinamide-phosphate is converted to the activated intermediate AdoCbi-GDP by the bifunctional enzyme Cob U. CobS catalyses the final step in adenosylcobalamin biosynthesis, which is the condensation of AdoCbi-GDP with α-ribazole to yield adenosylcobalamin.

Accepted name: sphingomyelin synthase
Reaction: a ceramide + a phosphatidylcholine = a sphingomyelin + a 1,2-diacyl-sn-glycerol
For diagram click here.
Glossary: sphingomyelin = a ceramide-1-phosphocholine
ceramide = an N-acylsphingoid. The fatty acids of naturally occurring ceramides range in chain length from about C16 to about C26 and may contain one or more double bonds and/or hydroxy substituents at C-2
sphingoid = sphinganine, i.e. D-erythro-2-aminooctadecane-1,3-diol, and its homologues and stereoisomers (see also Lip-1.4)
Other name(s): SM synthase; SMS1; SMS2
Systematic name: ceramide:phosphatidylcholine cholinephosphotransferase
Comments: The reaction can occur in both directions [3]. This enzyme occupies a central position in sphingolipid and glycerophospholipid metabolism [4]. Up- and down-regulation of its activity has been linked to mitogenic and pro-apoptotic signalling in a variety of mammalian cell types [4]. Unlike EC 2.7.8.3, ceramide cholinephosphotransferase, CDP-choline cannot replace phosphatidylcholine as the donor of the phosphocholine moiety of sphingomyelin [2].

Accepted name: α-glucan, water dikinase
Reaction: ATP + α-glucan + H2O = AMP + phospho-α-glucan + phosphate
Other name(s): starch-related R1 protein; GWD
Systematic name: ATP:α-glucan, water phosphotransferase
Comments: Requires Mg2+. ATP appears to be the only phosphate donor. No activity could be detected using GTP, UTP, phosphoenolpyruvate or diphosphate [1]. The protein phosphorylates glucans exclusively at the O-6 position of glucosyl residues [2]. The protein phosphorylates itself with the β-phosphate of ATP, which is then transferred to the glucan [1].

Accepted name: phosphoglucan, water dikinase
Reaction: ATP + [phospho-α-glucan] + H2O = AMP + O-phospho-[phospho-α-glucan] + phosphate
Other name(s): PWD; OK1
Systematic name: ATP:phospho-α-glucan, water phosphotransferase
Comments: The enzyme phosphorylates granular starch that has previously been phosphorylated by EC 2.7.9.4, α-glucan, water dikinase; there is no activity with unphosphorylated glucans. It transfers the β-phosphate of ATP to the phosphoglucan, whereas the γ-phosphate is transferred to water [1]. In contrast to EC 2.7.9.4, which phosphorylates the glucose groups in glucans predominantly on the O-6 position, this enzyme phosphorylates glucose groups in phosphorylated starch predominantly on O-3 [2]. The protein phosphorylates itself with the β-phosphate of ATP, which is then transferred to the glucan [1].

Accepted name: rifampicin phosphotransferase
Reaction: ATP + rifampicin + H2O = AMP + 21-phosphorifampicin + phosphate
For diagram of reaction click here.
Glossary: rifampicin = rifampin = 3-[(4-methylpiperazin-1-yl)iminomethyl]rifamycin
Other name(s): rifampin phosphotransferase; RPH
Systematic name: ATP:rifampicin, water 21-O-phosphotransferase
Comments: The enzyme, characterized from a diverse collection of Gram-positive bacteria, inactivates the antibiotic rifampicin by phosphorylating it at position 21. The enzyme comprises three domains: two substrate-binding domains (ATP-grasp and rifampicin-binding domains) and a smaller phosphate-carrying L-histidine swivel domain that transits between the spatially distinct substrate-binding sites during catalysis.
