Descriptor English: Nucleoside Q
Descriptor Spanish: Nucleósido Q
Descriptor nucleósido Q
Scope note: Nucleósido modificado que está presente en la primera posición del anticodón del ARNt-tirosina, ARNt-histidina, ARNt-asparagina y ARNt-ácido aspártico de muchos organismos. Se cree que interviene en la función reguladora del ARNt. Posteriormente, el nucleósido Q puede convertirse en nucleósido Q*, que tiene una molécula de manosa o de galactosa en la posición 4 de su anillo ciclopentenediol.

Scope note: A modified nucleoside which is present in the first position of the anticodon of tRNA-tyrosine, tRNA-histidine, tRNA-asparagine and tRNA-aspartic acid of many organisms. It is believed to play a role in the regulatory function of tRNA. Nucleoside Q can be further modified to nucleoside Q*, which has a mannose or galactose moiety linked to position 4 of its cyclopentenediol moiety.
