Names and origin

Protein namesRecommended name:
Penicillin-binding protein 2x
Short name=PBP-2x
Short name=PBP2x
Gene names
Name:pbpX
Ordered Locus Names:SP_0336
OrganismStreptococcus pneumoniae [Complete proteome] [HAMAP]
Taxonomic identifier1313 [NCBI]
Taxonomic lineageBacteria › Firmicutes › Lactobacillales › Streptococcaceae › Streptococcus

Protein attributes

Sequence length750 AA.
Sequence statusComplete.
Protein existenceEvidence at protein level

General annotation (Comments)

Function

Penicillin-binding proteins (PBPs) function in the late steps of murein biosynthesis. Beta-lactams inactivate the PBPs by acylating an essential serine residue in the active site of these proteins.

Subcellular location

Cell membrane; Single-pass membrane protein.

Miscellaneous

The mature form of PBP2x contains an unprocessed signal sequence followed by a membrane-anchoring segment.

Sequence similarities

Belongs to the transpeptidase family.

Contains 2 PASTA domains.
