Interacting selectively with a SMAD signaling protein.

The chemical reactions involving octopamine, 1-(p-hydroxyphenyl)-2-aminoethanol. The D enantiomer is about one-tenth as active as norepihephrine and is found in the salivary glands of Octopus and Eledone species.

The breakdown into simpler components of octopamine, 1-(p-hydroxyphenyl)-2-aminoethanol. The D enantiomer is about one-tenth as active as norepihephrine and is found in the salivary glands of Octopus and Eledone species.

The formation from simpler components of ethanolamine (2-aminoethanol), an important water-soluble base of phospholipid (phosphatidylethanolamine).

Catalysis of the carrier-mediated transfer of one or more substances across a membrane. Transport occurs in three ways: uniport, a single species is transported by facilitated diffusion in a process not coupled to the utilization of a primary source of energy; antiport, two or more species are transported in opposite directions in a tightly coupled process not directly linked to a form of energy other than chemiosmotic energy; and symport, two or more species are transported together in the same direction in a tightly coupled process not directly linked to a form of energy other than chemiosmotic energy.

Catalysis of the reaction: UDP-N-acetyl-D-glucosamine + lipopolysaccharide = UDP + N-acetyl-D-glucosaminyl-lipopolysaccharide.

A transporter of solutes that utilizes a carrier-mediated process to catalyze uniport, symport or antiport between aqueous phases on either side of a lipid membrane.

The chemical reactions involving phosphatidylethanolamine, any of a class of glycerophospholipids in which a phosphatidyl group is esterified to the hydroxyl group of ethanolamine. It is a major structural phospholipid in mammalian systems. It tends to be more abundant than phosphatidylcholine in the internal membranes of the cell and is an abundant component of prokaryotic membranes.

Catalysis of the transport of a single molecular species across a membrane; transport is independent of the movement of any other molecular species.
