Common name translation and transcription molecules?

The molecules that replicate DNA are collectively called "replisome".

Is there a similar term for all the molecules that synthesize proteins (both through translation and transcription)? Short of, of course, "protein synthesizers".

I can't seem to find the term, any feedback appreciated!

"Protein synthetic machinery" seems to work for searching.

The replisome is termed such because many of the components involved in DNA replication come together in time and space to form a complex of different proteins to carry out DNA replication. In contrast, the two steps of protein synthesis, transcription and translation, are carried out by distinct complexes (in fact, in eukaryotic cells, these two processes are carried out in completely separate compartments of the cell, with transcription occurring in the nucleus and translation occurring in the cytoplasm).

In eukaryotes, RNA polymerase II (itself a multiprotein complex) carries out transcription to produce mRNAs. During transcription, pol II (mainly thorugh its C-terminal domain) will recruit various other complexes (e.g. the spliceosome) to carry out the various RNA processing steps required for a pre-mRNA to be converted to a mature mRNA. Translation is carried out by the large protein-RNA complex called the ribosome.
