Protein existenceEvidence at transcript level.

General annotation (Comments)

Catalytic activity

ATP + D-ribose 5-phosphate = AMP + 5-phospho-alpha-D-ribose 1-diphosphate.

Cofactor

Binds 1 magnesium ion per subunit By similarity.

Sequence similarities

Belongs to the ribose-phosphate pyrophosphokinase family.

Sequence caution

The sequence BAD35420.1 differs from that shown. Reason: Erroneous gene model prediction.

Alternative products

This entry describes 2 isoforms produced by alternative splicing. [Align] [Select]
Isoform 2 (identifier: Q69XQ6-1)

This isoform has been chosen as the 'canonical' sequence. All positional information in this entry refers to it. This is also the sequence that appears in the downloadable versions of the entry.
Note: May be due to an intron retention. No experimental confirmation available.
Isoform 1 (identifier: Q69XQ6-2)

The sequence of this isoform differs from the canonical sequence as follows:
     340-399: SPPAIERLSG...RDGSVSSIFQ → RFGSWFIVTS...DQYKNDRVEQ
