Four Steps for bacterial transcription

1. Promoter search->closed promoter complex -> open promoter complex

2. Abortive transcription->Promoter Escape->Initiation from +1 TSS 

3. Elongation

4. Termination

Glycine decarboxylase GDC multienzyme complex, present in large concentrations in the matrix of plant mitochondria, comprises four proteins, named 

H-protein (a lipoamide-containing polypeptide), 

P-protein (a 200 kDa, homodimer, pyridoxal phosphate-containing protein),

T-protein (a folate-dependent protein), and 

L-protein (a flavin adenine nucleotide–containing protein
