The formation from simpler components of purine bases, one of the two classes of nitrogen-containing ring compounds found in DNA and RNA, which include adenine and guanine.

Any collagen polymer which links one collagen assembly, such as a collagen fibril or sheet, to other structures.

positive regulation of translational initiation by iron

Any process involving iron that activates or increases the rate of translational initiation.

Any collagen polymer in which collagen triple helices associate to form sheet-like networks.

Any process that modulates the frequency, rate or extent of embryonic development.

The chemical reactions involving a nucleoside, a nucleobase linked to either beta-D-ribofuranose (ribonucleoside) or 2-deoxy-beta-D-ribofuranose, (a deoxyribonucleotide), e.g. adenosine, guanosine, inosine, cytidine, uridine and deoxyadenosine, deoxyguanosine, deoxycytidine and thymidine (= deoxythymidine).

The chemical reactions involving a nucleotide, a nucleoside that is esterified with (ortho)phosphate or an oligophosphate at any hydroxyl group on the glycose moiety; may be mono-, di- or triphosphate; this definition includes cyclic-nucleotides (nucleoside cyclic phosphates).

The selective interaction of a protein with specific molecules in the cytoplasm, thereby inhibiting its transport into other areas of the cell.

Any process that modulates the frequency, rate or extent of the chemical reactions involving nucleosides.

The chemical reactions involving any ribonucleoside, a nucleoside in which purine or pyrimidine base is linked to a ribose (beta-D-ribofuranose) molecule.

positive regulation of protein transport

Any process that activates or increases the rate of the directed movement of a protein into, out of, within or between cells.

Any process that modulates the frequency, rate or extent of the directed movement of a protein into, out of, within or between cells.

negative regulation of protein transport

Any process that stops, prevents or reduces the rate of the directed movement of a protein into, out of, within or between cells.
