Any process that modulates the binding and fusion of a sperm to the oocyte plasma membrane.

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

The synthesis of (S,Z)-S-(2-aminovinyl)cysteine forming an intra-polypeptide cross-link between serine and cysteine.

Activation of an amino acid for incorporation into a peptide by a nonribosomal process.

The modification of an amino acid to an active form, for incorporation into a peptide, protein or other macromolecule.

The addition of one or more alpha-linked glutamyl units to the gamma carboxyl group of peptidyl-glutamic acid.

The synthesis of aminoacyl tRNA by the formation of an ester bond between the 3'-hydroxyl group of the most 3' adenosine of the tRNA, to be used in nonribosomal peptide synthesis.

The addition of glycyl units covalently bound to the gamma carboxyl group peptidyl-glutamic acid.

The racemization of peptidyl-asparagine.

The initial developmental process that will lead to the formation of the vertebrate inner ear. The otic placode forms as a thickening of the head ectoderm adjacent to the developing hindbrain.

The chemical reactions and pathways resulting in the formation of dolichyl diphosphate, a phosphorylated dolichol derivative.

The covalent transfer of a methyl group to C-5 of cytosine that contributes to the establishment of DNA methylation patterns in the gamete.

Activation of an amino acid for incorporation into a peptide by a nonribosomal process, catalyzed by subunits of nonribosomal peptide synthase. The amino acid is adenylated at its carboxylate group (ATP-dependent) then transferred to the thiol group of an enzyme-bound phosphopantetheine cofactor.
