Genes in this functional category

ppGpp synthesis and degradation

• RelA
• YjbM
• YwaC

c-di-AMP synthesis

• DisA
• CdaA
• CdaS

Control of c-di-AMP synthesis

• CdaR

Note that c-di-AMP is essential for the growth of B. subtilis, but accumulation of the nucleotide is detrimental as well PubMed

c-di-AMP degradation

• GdpP

c-di-GMP degradation (presence of an EAL domain)

• YkoW
• YkuI
• YuxH

c-di-GMP synthesis/ based on similarity (presence of a GGDEF domain)

• GdpP
• YdaK
• YhcK
• YkoW
• YtrP (this enzyme may be inactive due to the lack of important residues)

Targets of signalling nucleotides

• ppGpp targets
  • GdpP
  • Gmk
  • GuaB
  • HprT

• c-di-GMP targets
  • YpfA (contains a PilZ domain)
