OBSOLETE. Hydrophobic glycoprotein to which 11-cis-retinal binds as a Schiff base (in rhodopsin) or 3,4-didehydro-11-cis-retinal binds as a Schiff base in cyanopsin and porphyropsin.

The progression of a nephron tubule over time, from its initial formation to the mature structure. A nephron tubule is an epithelial tube that is part of the nephron, the functional part of the kidney.

A protein complex that possesses methane monooxygenase activity; dimeric and trimeric complexes have been characterized.

The progression of the glomerulus of the pronephric kidney over time from its initial formation until its mature state. The pronephric glomerulus is part of the pronephric nephron and is restricted to one body segment.

The progression of the glomerulus over time from its initial formation until its mature state. The glomerulus is a capillary tuft which forms a close network with the visceral epithelium (podocytes) and the mesangium to form the filtration barrier and is surrounded by Bowman's capsule in nephrons of the vertebrate kidney. The glomerulus is part of the nephron and is restricted to one body segment.

OBSOLETE. Combining with an opioid to initiate a change in cell activity, with the pharmacological characteristics of X-opioid receptors.

The process whose specific outcome is the progression of the pronephric duct over time, from its formation to the mature structure. The pronephric duct collects the filtrate from the pronephric tubules and opens to the exterior of the pronephric kidney.

The process whose specific outcome is the progression of a nephric duct over time, from its initial formation to a mature structure. A nephric duct is a tube that drains a primitive kidney.

OBSOLETE. (Was not defined before being made obsolete).

Catalysis of the reaction: S-adenosyl-L-methionine + tRNA = S-adenosyl-L-homocysteine + tRNA containing thymine at position U54 of a transfer RNA. This occurs in most Gram-negative bacteria, some archae, and eukaryotes.

Catalysis of the transfer of a methyl group from 5,10-methylenetetrahydrofolate to the C5 atom of the uridine residue at position 54 in a tRNA molecule. This occurs in most Gram-positive bacteria and some Gram-negative bacteria.

Catalysis of the reaction: acetyl phosphate + H(2)O + NH(4)(+) + thioredoxin disulfide = glycine + H(+) + phosphate + thioredoxin.

Any process that increases the rate of growth of all or part of an organism.

A ribonuclease P complex that contains a single RNA molecule that is necessary and usually sufficient for catalysis, and a single protein molecule. Examples of this complex are found in Bacterial species.

Any process that mediates the transfer of information from one cell to another and contributes to the progression of the pronephros over time, from its formation to the mature organ.

Any process that results in a change in state or activity of a cell or an organism (in terms of movement, secretion, enzyme production, gene expression, etc.) as a result of detecting the defenses of the host organism. The host is defined as the larger of the organisms involved in a symbiotic interaction.

Attaching of a chitin-containing cuticle to the epithelium underlying it. An example of this process is found in Drosophila melanogaster.

Any developmental process that results in the creation of defined areas or spaces within the kidney to which cells respond and eventually are instructed to differentiate.

OBSOLETE. Attaching of a protein-based cuticle to the epithelium underlying it.
