tripartite ATP-independent periplasmic transporter complex

A complex consisting of two membrane proteins and one extracytoplasmic solute receptor. Such transporters transport a variety of substrates without direct ATP power, instead using energy from ion gradients.

DNA ligase (ATP) activity

Catalysis of the reaction: ATP + deoxyribonucleotide(n) + deoxyribonucleotide(m) = AMP + diphosphate + deoxyribonucleotide(n+m).

2-oxopropyl-CoM reductase (carboxylating) activity

Catalysis of the reaction: acetoacetate + coenzyme M + NADP+ = 2-oxopropyl-coenzyme M + CO2 + NADPH.

DNA ligase (NAD+) activity

Catalysis of the reaction: NAD+ + deoxyribonucleotide(n) + deoxyribonucleotide(m) = AMP + nicotinamide nucleotide + deoxyribonucleotide(n+m).

obsolete thiol-driven fumarate reductase activity

OBSOLETE. Catalysis of the reaction: fumarate + coenzyme M + coenzyme B = succinate + coenzyme M + coenzyme B + heterodisulfide.

2-(R)-hydroxypropyl-CoM dehydrogenase activity

Catalysis of the reaction: 2-(R)-hydroxypropyl-coenzyme M + NAD+ = 2-oxopropyl-coenzyme M + H+ + NADH.

2-(S)-hydroxypropyl-CoM dehydrogenase activity

Catalysis of the reaction: 2-(S)-hydroxypropyl-coenzyme M + NAD+ = 2-oxopropyl-coenzyme M + H+ + NADH.

epinephrine binding

Binding to epinephrine, a hormone produced by the medulla of the adrenal glands that increases heart activity, improves the power and prolongs the action of muscles, and increases the rate and depth of breathing. It is synthesized by the methylation of norepinephrine.

RNA ligase (ATP) activity

Catalysis of the reaction: ATP + (ribonucleotide)n-3'-hydroxyl + 5'-phospho-(ribonucleotide)m = (ribonucleotide)n+m + AMP + diphosphate.

obsolete meiosis II M phase

OBSOLETE. M phase during meiosis II.
