The aggregation, arrangement and bonding together of proteins, DNA, and RNA molecules to form a protein-DNA-RNA complex.

Any process involved in the melting of the DNA hybrid of the core promoter region within the transcriptional closed complex of an RNA polymerase preinitiation complex (PIC) to produce an open complex where the DNA duplex around the transcription initiation site is unwound to form the transcription bubble.

Any process involved in the melting of the DNA hybrid of the core promoter region within the transcriptional closed complex of an RNA polymerase II preinitiation complex (PIC) to produce an open complex where the DNA duplex around the transcription initiation site is unwound to form the transcription bubble.

A process that mediates the transition from the initiation to the elongation phases of transcription by RNA polymerase III, generally including a conformational change from the initiation conformation to the elongation conformation. Promoter clearance often involves breaking contact with transcription factors involved only in the initiation phase.

A process that mediates the transition from the initiation to the elongation phases of transcription by RNA polymerase II, generally including a conformational change from the initiation conformation to the elongation conformation. Promoter clearance often involves breaking contact with transcription factors involved only in the initiation phase and making contacts with elongation specific factors.

Binding to a component of the basal transcription machinery which is composed of a bacterial-type RNA polymerase core enzyme and a sigma factor, the minimal set of factors required for formation of the preinitiation complex (PIC) by a bacterial-type RNA polymerase.

Binding to a component of the basal transcription machinery which is composed of the RNA polymerase core enzyme and the basal transcription factor(s), the minimal set of factors required for formation of the preinitiation complex (PIC) by the RNA polymerase.

The directed movement of L-alanine, the L-enantiomer of 2-aminopropanoic acid, into, out of or within a cell, or between cells, by means of some agent such as a transporter or pore.

The directed movement of alanine, 2-aminopropanoic acid, into, out of or within a cell, or between cells, by means of some agent such as a transporter or pore.

The directed movement of S-methylmethionine into, out of or within a cell, or between cells, by means of some agent such as a transporter or pore.

The directed movement of branched-chain amino acids into, out of or within a cell, or between cells, by means of some agent such as a transporter or pore. Branched-chain amino acids are amino acids with a branched carbon skeleton without rings.

The process in which aspartate is transported across a lipid bilayer, from one side of a membrane to the other.

The directed movement of L-cystine (also known as dicysteine) into, out of or within a cell, or between cells, by means of some agent such as a transporter or pore.
