Categories of SUIT protocols
Description
Categories of SUIT protocols group SUIT protocols according to all substrate types involved in a protocol, independent of titrations of inhibitors which block the oxidation of the substrates present. ROX states may or may not be included in a SUIT protocol, which does not change its category. » MiPNet article

Abstract: There are many ways to define groups of SUIT protocols. Since the complexity of SUIT protocols is primarily determined by the large number of possible substrate states, and to a lesser extent by the smaller number of possible coupling states, a relevant type of categories of SUIT protocols considers the substrate types involved. Whereas the SUIT protocol names include all specific substrates applied in the SUIT protocol, the categories of SUIT protocols reduce this diversity to substrate types.

Towards a library of SUIT protocols
- At the present stage of development of the 'library of SUIT protocols' as part of the MitoFit Quality Control System, five respiratory substrate types are considered:
- On the pathway level of converging NADH- and FADH2-linked dehydrogenases, including the TCA cycle and beta-oxidation:
- At the present stage of development of the 'library of SUIT protocols' as part of the MitoFit Quality Control System, five respiratory substrate types are considered:
- N: NADH-linked substrates (CI-linked)
- F: FADH2-linked substrates (FAO)
- On the pathway level of electron transfer complexes converging at the Q-junction:
- S: Succinate (CII-linked)
- Gp: Glycerophosphate (CGpDH-linked)
- On the single step level of cytochrome c oxidase (CIV), the terminal step in the aerobic electron transfer system:
- Tm: Artificial electron transfer susbstrate TMPD (Tm) maintained in a reduced state by ascorbate (As) and reducing cytochrome c as the substrate of CIV.
SUIT-Catg: single substrate type
- N - ETS-level 4
- F - ETS-level 4
- S - ETS-level 3
- Gp - ETS-level 3
- Tm - ETS-level 1. Tm can be included or excluded at the end of a SUIT protocol. To simplify the categorization, Tm is not considered in this system of SUIT protocols.

SUIT-Catg: multiple substrate types without N
- F and S without N are problematic substrate states due to accumulation of Oxa or Acetyl-CoA. Therefore, addition of malate alone (M without P or G) is not considered as substrate type N. However, high mt-malic enzyme activity requires a change of this concept, when M alone represents an ETS ccompetent substrate state. Low concentration of M may be used to support FAO, whereas a higher concentration of M may be required for N-linked respiratory capacity to override FAO capacity; this needs corresponding kinetic analyses (SUIT test protocols).
