Organism

Synechococcus elongatus (strain PCC 7942) (Anacystis nidulans R2) [Complete proteome] [HAMAP]

Taxonomic identifier

1140 [NCBI]

Taxonomic lineage

cellular organisms › Bacteria › Cyanobacteria › Oscillatoriophycideae › Chroococcales › Synechococcus › Synechococcus elongatus

Protein attributes

Sequence length	59 AA.
Sequence status	Complete.
Protein existence	Evidence at protein level

General annotation (Comments)

Function	Involved in phycobilisome (PBS) degradation during nutrient deprivation. May mark the PBS for degradation by covalent association with PBS components or may disrupt the PBS via ionic interactions.
Induction	Present at very low levels in nutrient-replete cells, and at 50-fold higher levels in nitrogen- or sulfur-deprived cells and to a variable extent (<10-fold) during phosphorus deprivation.
Sequence similarities	To chloroplast ycf18.
