CC   -!- FUNCTION: A C-terminal pseudogene fragment of BcsQ, which has a
CC       premature stop codon at position 6 of the intact protein. The mutation
CC       prevents cellulose synthesis, and has polar effects on transcription of
CC       downstream gene bcsA and probably also bcsB, bcsZ and bcsC
CC       (PubMed:24097954). When the reading frame is restored cellulose
CC       biosynthesis is also restored, see (AC P0DP92) for an intact protein.
CC       May play a role in subcellular localization of an active cellulose
CC       biosynthesis apparatus at the bacterial cell pole (By similarity).
CC       {ECO:0000250|UniProtKB:P0DP92, ECO:0000305|PubMed:24097954}.
CC   -!- INDUCTION: Part of the yhjR-bcsQABZC operon (PubMed:24097954).
CC       {ECO:0000269|PubMed:24097954}.
CC   -!- MISCELLANEOUS: Cellulose production is abolished in E.coli K12 /MG1655
CC       and W3110 due to a premature stop codon in this gene. The sequence
CC       given here starts on a GTG codon 6 nucleotides downstream of the
CC       premature stop codon. {ECO:0000269|PubMed:24097954}.
CC   -!- SIMILARITY: Belongs to the BcsQ family. {ECO:0000305}.
CC   -!- CAUTION: Could be the product of a pseudogene. The protein is missing 8
CC       N-terminal amino acids due to a premature stop codon; when the reading
CC       frame is restored strain W3110 synthesizes cellulose. See (AC P0DP92)
CC       for a functional intact protein. {ECO:0000305|PubMed:24097954}.
