Clusters of Characterized Proteins

Clustering the characterized proteins for PSSH (O-phosphoserine sulfhydrylase) in L-cysteine biosynthesis

Or see other characterized proteins similar to PSSH

Or see all steps for L-cysteine biosynthesis

Or cluster curated proteins matching a keyword

Definition of PSSH

• Curated proteins or TIGRFams with EC 2.5.1.65
• Comment: PSSH is similar to cysK or Mt_cysM, so might need ignore clauses?
